I'm left handed and there are quite a few lefties in my family, including my mom, grandpa, and brother.
I'm OCD, and some of my quarks are that I don't like when my food is touching, I hate using sponges and rags to clean, I wash my hands a lot, and things have to be even. I could go on...
I hate taking selfies because I'm a perfectionist, so posting 1 cute selfie takes an hour of me posing in front of a mirror. It's exhausting.
I like to eat ice cream during winter, and drink hot chocolate in the summer. I think it's stupid, but I can't help that I crave them during those seasons.
