I've heard several different comments.
1. Are you a boy or a girl? This is usually by kids who seem to think all girls must have long straight hair. Occasionally adults also think I am a boy, but if they'd use their eyes it would be obvious that some parts of my anatomy make it obvious I'm a girl.
2. Afro is one of I've heard quite often.
3. Because I grew up in the 80's and Saved by the Bell was popular they used to tease me and call me Screech.
4. It was also easy to throw things in my hair because it would stick there.
I really didn't have a bad time of it. It just the few times people said something really stuck with me.
