Being stereotyped as a gamer that spends 100% of his life playing nothing but games and nothing else. No social life, not working on art, or any of the sort. There is something called a job that gets in my way you know.
I'm actually trying to make plans for my life and predict when I can get the best income and all sorts of things, as well as trying to time things so I can freelance some design work while working at the store, so I can pull in a slightly larger income than I usually do. Much harder than it sounds. Plus, I have literally thousands of games on my machine, and I barely touch them, for what it's worth (plus, I've been playing DF more anyway).
And another pet peeve of mine is when something is no longer mine (by ownership) due to priority or use. Example: My car. My car is mine by ownership and everything, but recently (actually, for the past 6 months), since it's one of the only working cars in my household, my sister has pretty much turned it into hers (even if I need it to go to work, she wouldn't even let me use it to get there, even if her time to use it is an hour after I return home). The thing is not mechanically maintained, nor kept clean; the thing is practically a pack mule; and I use it 4 times a month if I'm lucky, and I'm still making majority payments on it (insurance, registration, gas) regardless if I address it or not. The only reason I'm not maintaining it is because it's "no longer" mine. Not my fault if it breaks down. Just about everything else in it turned into total crap; I actually am willing to completely disown my car; it's that bad off.
And one last one for the moment, since I noticed. Noticing my own redundant speech patterns.
