3. "Always tell a child who is wearing a helmet how cool you think their helmet is. It will encourage them to always wear it in the future."
4. "When you don't have all the facts, try to give people the most generous reason you can for their behavior. Annoyingly slow driver? Maybe it's a mom with a birthday cake in the back. This mindset will gradually make you less reactive and more compassionate."
5. "Do not try to be the man your father would want you to be. Be the man you would like your son to be. It more clearly defines your own convictions, desires, goals and motivates you to be your best."
6. "When a friend is upset, ask them one simple question before saying anything else: 'Do you want to talk about it or do you want to be distracted from it?'"
7. "After a bad breakup, do 10 things that your ex would never do with you. You'll feel better and realize how much of yourself was being held back."
8. "Before you give your child a unique name, try it out first. Use it on food orders, reservations, appointments where applicable, etc. It’ll give you a glimpse of what they’ll deal with when they’re older and could prevent future issues."
9. "If you need to cancel a hotel reservation but are unable to because of a 24-hour policy, call the company and move your reservation to a later date. Call back within a few days and cancel for no charge."
10. "If you tell someone you need to talk to them, for the love of God give some indication of what you need to talk about, or at least that it's not bad news."

12. "Don't just let kids win at games. You can slow it down, you can teach them strategy, but keep it real. Someday, they will beat you fair and square, and it will be a moment they always remember with pride."
13. "When cooking things on aluminum foil, first scrunch the foil up, then lay it loosely flat again out on your baking tray. The juices will stay put—and the food will not stick to the foil half as much, if at all."
14. "If you think of a good idea, write it down. Your brain will try to trick you into thinking you will remember it later, but it's a liar! Therefore: Write it down!"
15. "It takes 4 minutes a day and almost no cost to maintain dental hygiene. It takes a lifetime and a lot of money to correct it. 2-minute brush and mouthwash in the AM, 2-minute brush and floss in the PM."
16. "Don’t wait until you have 'time' to start a fitness program. Because then when you get busy again, you’ll stop. The best time to start is actually when you’re busy. Learning how to fit it in when times are tough means you’ll stick with it over the long haul."
17. "When using text messages or IMs for business, say everything you need to say in the first message. Don’t just say 'hi' or 'hey' or 'are you there' or 'are you busy.'"
18. "Instead of feeling that you've blown the day and thinking, 'I'll get back on track tomorrow, think of each day as a set of four quarters:
• Morning• Midday• Afternoon• Evening
If you blow one quarter, you get back on track for the next quarter."
19. "Many problems in marriage are really just problems with being a bad roommate. Learn how to be a good roommate, and it will solve many of the main issues that plague marriages. This includes communicating about something bothering you before you get too angry."

There's a reason why some people can perfectly copy accents, and others can't
Turns out, there's a neurodivergent link.
A woman in black long sleeve shirt stands in front of mirror.
Have you ever had that friend who goes on vacation for four days to London and comes back with a full-on Queen's English posh accent? "Oooh I left my brolly in the loo," they say, and you respond, "But you're from Colorado!" Well, there are reasons they (and many of us) do that, and usually it's on a pretty subconscious level.
It's called "accent mirroring," and it's actually quite common with people who are neurodivergent, particularly those with ADHD (Attention Deficit Hyperactivity Disorder). According Neurolaunch, the self-described "Free Mental Health Library," "Accent mirroring, also known as accent adaptation or phonetic convergence, is the tendency to unconsciously adopt the accent or speech patterns of those around us. This linguistic chameleon effect is not unique to individuals with ADHD, but it appears to be more pronounced and frequent in this population."
Essentially, when people have conversations, we're constantly "scanning" for information—not just the words we're absorbing, but the inflection and tone. "When we hear an accent, our brains automatically analyze and categorize the phonetic features, prosody, and intonation patterns," writes Neurolaunch. For most, this does result in copying the accent of the person with whom we're speaking. But those with ADHD might be more sensitive to auditory cues. This, "coupled with a reduced ability to filter out or inhibit the impulse to mimic…could potentially explain the increased tendency for accent mirroring."
While the article explains further research is needed, they distinctly state that, "Accent mirroring in individuals with ADHD often manifests as an unconscious mimicry of accents in social situations. This can range from subtle shifts in pronunciation to more noticeable changes in intonation and speech rhythm. For example, a person with ADHD might find themselves unconsciously adopting a Southern drawl when conversing with someone from Texas, even if they’ve never lived in the South themselves."
People are having their say online. On the subreddit r/ADHDWomen, a thread began: "Taking on accents is an ADHD thing?" The OP shares, "My whole life, I've picked up accents. I, myself, never noticed, but everyone around me would be like, 'Why are you talking like that??' It could be after I watched a show or movie with an accent or after I've traveled somewhere with a different accent than my 'normal.'
They continue, "Apparently, I pick it up fast, but it fades out slowly. Today... I'm scrolling Instagram, I watch a reel from a comedian couple (Darcy and Jeremy. IYKYK) about how Darcy (ADHD) picks up accents everywhere they go. It's called ADHD Mirroring??? And it's another way of masking."
(The OP is referring to Darcy Michaels and his husband Jeremy Baer, who are both touring comedians based in Canada.)
Hundreds of people on the Reddit thread alone seem to relate. One comments, "Omfg I've done this my whole life; I'll even pick up on the pauses/spaces when I'm talking to someone who is ESL—but English is my first language lol."
Sometimes, it can be a real issue for those around the chameleon. "I accidentally mimicked a waitress's weird laugh one time. As soon as she was out of earshot, my family started to reprimand me, but I was already like 'oh my god I don’t know why I did that, I feel so bad.'"
Many commenters on TikTok were shocked to find out this can be a sign of ADHD. One jokes, "Omg, yes, at a store the cashier was talking to me and she was French. She's like 'Oh are you French too? No, I'm not lol. I'm very east coast Canada."
And some people just embrace it and make it work for them. "I mirror their words or phrase! I’m 30. I realized I start calling everyone sweetie cause my manager does & I work at coffee shop."
