My ex once told me that my hair looks like Russell Brand's. I was so offended, that man is not attractive and it looks like a bird nested on his head!
And my ex actually thought I'd take this as a compliment.
Other than that, in middle school people would spread rumors that my hair was a wig. I'm not sure where that idea came from, but it lead to kids trying to "pull it off". After a while it didn't bother me so much cause I started to see it as a compliment. It meant my curls looked too gorgeous to be real!
