Naturals: they're all around the four type and I have three of them. Another I don't talk to much but she's also natural. This other girl a grade lower and a few others I can't think of.
Curlies: too many to count people at my school they do prefer straight but tons wear it curly and straighten on occasion or just don't do anything. Though most wear it curly most people are really pro straight and think that's the prettiest.
