how to make an enemy in just two days

okay, so i'm in the restroom at work, washing my hands. a perfectly normal every day type thing. and this is just another case of me not understanding what it is about me that makes people think that i want to be approached while in a restroom, but whatever. it happens to me all the time! anyway. me, washing the hands. well in walks our custodian/janitor/whatever the pc term is and he gives me a look. "um, hey" i say, washing faster. and he flips out because i'm using the clean and germ free paper towels from the wall thingy, rather than the soiled looking half-used roll that is sitting on the counter. he informs me that i am to use those first. "listen pal, i don't tell you how to scrub a toilet, so i don't need you telling me how to dry my hands." f.r.e.a.k. the next roll i see just sitting there is going in the trash. i swear he finds me every single day, appearing out of nowhere, and we have some sort of weird run in. he's my very own janitor a la scrubs, excellent show by the way. but it's gotten to the point that when i see him coming i run the other way. i don't know, maybe he's mad because a few weeks ago he asked me to hold the elevator for him and i purposely let the doors close. i hid in the corner so that only my friend could be seen by him and i just let the doors close. i wasn't about to share the ride with his bucket-o-filth that he was dragging along behind him. so now i have the feeling that he's out to get me. he plays these little mind games with me every day and asks me if i need supplies and when i say yes he leaves to go get them but never returns! never, not once. i mean come on, that's your job. so now it's my mission to break his spirit. well not really, but an evil plot now and then will help the day pass by a little faster.
