More quirks:
I can also be a little OCD as well when it comes to writing. I have to make sure that my punctuation doesn't line up with other punctuation. It drives nuts when I worry over this, but I can't help it. I wish I could just write normally and not panic over this. I even do it when I'm just writing as I am at the moment. It's literally just one thing that will cause me to twitch and have to correct so much. So, in order to do so, I often add more words to a paragraph to make sure it doesn't happen. x_x
Another semi-quirk is my poor motor coordination. If I bend one finger down, they all go down. I also hold pencils incorrectly and only type with two fingers. The reason is because of poor motor coordination. As I said before, my fingers can't bend or reach keys without unintentionally hitting other keys on the keyboard. So, I find it easier to type with just two fingers instead. Believe me, I can type really fast with just two alone. That's one of the reasons why I make so many typos that I'm sure you've seen in previous posts. :P My poor motor coordination is either due to having dyspraxia or autism.
Also, this is more of a previous quirk I had... I used to wear hoodies ALL THE TIME. It didn't matter what the weather was like outside. It could be steaming hot, and I would still have a hoodie on. I did this more during high school though because I believe it was for comfort reasons. I hated high school, so I had to have something to comfort me without getting teased for carrying around plushies during class time or whatever. :x
