They're called 'electric highways,' and they might change everything about how we drive.

One generation's texting habit that baffles every generation is the Boomers' seemingly excessive use of ellipses. Do you have more to say, Aunt Judy, or did you just accidentally press the period key too many times? Maybe it's for a dramatic pause or to put emphasis on a point? This is truly a mystery that leaves every generation below them confused about what is meant by the dreaded "dot dot dot."

Texting etiquette differs with every generation. Gen X and most Millennials use fairly proper grammar and punctuation throughout a text message exchange. Every new sentence starts with a capital letter, there are strategically placed Oxford commas to ensure there's little room for misunderstandings, and sentences end with an appropriate punctuation mark.

When it comes to Gen Z, they find that ending text messages with proper punctuation indicates that the person they're texting is being passive-aggressive. They also text in shorthand and emojis that can feel a bit like you need a special decoder ring to decipher the messages. But texting in an encrypted way can be chalked up to youth, though the same can't be said when it comes to Boomers. Or can it?

Harvard linguist and author of the book Algospeak, Adam Aleksic, breaks down why so many Boomers use ellipses when texting. It's surprisingly not as complicated or dramatic as one may imagine. In a viral video posted last year on TikTok, Aleksic explains his theory for the texting etiquette of Boomers.

"You know how older people tend to use the 'Boomer ellipses' whenever they're texting? There's always a random 'dot dot dot' in the middle of their messages?" Aleksic asks. "Well, that's because they grew up following different rules for informal communication. Nowadays, if you want to separate an idea, you just press enter and start a new line with a new thought, but it made less sense to do that for writing postcards or letters, where you had to save space, so people back in the day learned to separate thoughts by using ellipses."

Aleksic explains that this is also true for when phones first started allowing text messaging. You were charged by the message, so ellipses made it more efficient to convey all the thoughts in one message instead of multiple ones. SMS texting also had a character limit, unlike current phones, where you can essentially write a novella in a single message without your phone automatically breaking it up.

Today's texting standards typically mean people separate their thoughts by sending multiple messages for separate thoughts, though that annoys some people. If separating thoughts means you'll be sending no less than five texts in quick succession, it's likely best to just space down to make the text longer, rather than bombarding an unsuspecting friend.

When it comes down to it, younger generations have adapted to the new standard, embracing the unlimited text option, while Boomers haven't. Due to this discrepancy in text etiquette, the ellipses used by Boomers throw people for a loop.

"That means the Boomer ellipses became redundant, which is why they cause confusion today. They violate what we call 'the maximum quantity;' they add more information than necessary, so they appear to imply something more than the intended meaning. Most of the time, that comes off to younger people as hesitation, annoyance, or passive aggressiveness because that's how we use the ellipses," the linguist shares.

So, no, your grandma isn't mad at you or avoiding telling you something; according to Aleksic, she's just trying to send you multiple messages in one. There's no hidden emotion behind the ellipses for Boomers; it's simply a habit left over from their younger years.
