-crack my knuckles
-crack my neck from side to side
-My nervous child-hood habit: I tend to pick at the skin on my fingers, mostly just my thumbs.
-I don't like having anything on my hands, as in, anything powdery, sticky, lotion-ie, etc. I wash my hands a lot. I carry that alcohol-based hand sanitizer around with me constantly, but it just isn't the same.
-I get snippy when I have to repeat myself, which is a really bad habit
-I do things really quickly (but thoroughly), like cleaning, cooking, working and such. I can get snippy if someone gets in my way or slows me down. Hence why I loathe group projects in college, I clash with people who have a different cooking style when trying to cook with me, etc. That's a bad habit, I've driven my SO out of the kitchen on numerous occasions, and have taken over and completed group projects alone at times (which doesn't bother some people, but I won't do it if it does bother a group). It's a bad/controlling habit regardless.
-I don't consider procrastination in my major a bad habit; my best papers are turned out at 3am in the morning. It's the ones I do a few weeks before that end up bombing! I accepted the benefits of procrastination a couple years ago
-I run around a lot, sometimes skipping meals, which is a bad habit for me because when I'm hungry I get, again, snippy.
-I'm really bad about not throwing dead roses out, lol. I like the look of them dried out too, so I tend to leave them in the house once they've died. Kinda morbid, lol, but orange roses turn this lovely beach color and bright pinks turns a dark pink-red, etc.
