It's PAYBACK Time

There's a guy on my floor here in LRH who's been spuradically playing jokes on me. He does one of two main things to make me mad. Mostly, these pranks occur at night- right around the time I'm sleeping or taking a shower. Boy, does that get on my nerves! When these pranks are pulled, I know that I shouldn't take it- yet, I shouldn't allow him to taunt me like that either.
Last night, for instance, someone loudly POUNDED on my bedroom door. I was already asleep, so I didn't even bother getting up to see who was knocking on my door. I basically slept through the noise, ignored it long enough until it had stopped for good. There's only one person who I'm pretty certain caused all that racket, and he must be STOPPED.
