I've found that lately I've been either just agitated or annoyed more than usual. Sounds very "emo" -esque to say, but even people having happy conversations around me just seems to make me annoyed.
Occasionally, my dorm mates will bring in friends of their own (we have a relatively bigger dorm so with a coach and tv and such, which allows for more people to be present). And it annoys me so bad that I can hear everything they talk or laugh about, despite me asking them to be quite multiple times. (Tempted to call RA's about a noise problem as they technically aren't supposed to be there but I don't really want to be an asshole haha.)
