Well, my temper. What can I say? I'm a Scorpio, and thus, I can be a blunt, honest bitch!
There are some times where I can hold a grudge for far too long, even though for most things, I'd forgive people if they just owned up to it in an instant. Yeayea, wasted energy. I'm a Scorpio, AHAHAHA. Stingsting!
I also really get pissed if people don't even have decent common courtesy. That pisses me off.
Also, my OCD and ADHD don't help me, and cause many of my problems, but I can't really do shit about that, soooo, WHATEVER THERE.
