I was once discussing a school project with my teacher and suddenly, she went quiet and asked: "Is your hair that curly naturally" and I was like "umm, yes..." and then she said "It's so beautiful! Like real corkscrews. So unfair!"
And another time she told me "You know... if I was to choose whatever hair I wanted, I would choose yours! It's soo beautiful!"
Made my day
Otherwise, I mostly get compliments from my friends... and the girls in school use to tell me that my hair's "just get curlier and curlier every day". I guess that's meant as a compliment :P
