An article struck a nerve with some, sparking an important conversation.
There's an article making the rounds on social media called, "How to Talk to a Woman Who is Wearing Headphones."
It's written by self-described dating and relationship expert Dan Bacon, and it's equal parts funny, sad, and scary. The truth is that if a woman is wearing headphones, she probably (OK, pretty much definitely) doesn't want to be interrupted for a chat with a stranger.
Leaving someone wearing headphones alone is just one of those unwritten rules of polite society. Headphones are basically a universal sign meaning "Leave me the eff alone."
