This irks me. At least you can respect the people who have the courage (or the temerity?) to approach a person about an issue that directly concerns them. Even if someone is rude when they approach me about my hair at least that person went to the source and didn't speculate about it in a full blown conversation on the sidelines with another person in a public setting when they think I have bricks for ear drums!
And don't get me started on the ones who just straight up invite themselves to play massage therapist with their potentially dirty fingers all up in a scalp. It's like...okay, you're curious, I understand that. But was it really necessary to violate my personal space, especially without my consent? Is it that serious? Not to mention the entire situation is painfully awkward.
Sure, anyone can make it their business to find out if my hair is real or not, but I'm down to check anyone who crosses that line.
