There's something about night that just messes me up. Typically I'll either become extremely delirious to the point where I can't stop laughing or I'll become extremely bitter, sometimes to the point of suicidal thoughts, as has been the case for the past few hours.
Other times still I'll become extremely paranoid. This, coupled with my extraordinarily sensitive hearing, often leads to me thinking that somebody's broken into the place. After hearing a loud noise, I'll go around with a flashlight (and knife) and inspect each room thoroughly. Although, lately I have grown sick of this, and my new rule is to ignore loud sounds (almost all of which originate from across the street, or even across the block). At this point I figure I'd rather just be stabbed to death by a trespasser than go through the same annoying "clear out the rooms" routine every time I hear a crash. It's just not worth it.
