I'm Jewish but not a single person in my family other than me has curly hair. Everyone elses is stick straight- my mom, my brother, my dad (whose not Jewish, but you can't have everything), my grandparents, my cousins.. its nuts. So I went most of my life brushing my hair to try to get it to be straight like all of theirs thinking I just wasn't brushing enough. Come to find out that hey! I'm a curly!
But I totally embrace my utter Jewishness. I look as Jewish as can be... and growing up in the deep South made that an interesting experience. I'm going to a Jewish college though and I've never met so many people with curly hair! It's great.
