You know what I really hate?

I hate it when the people in the lab who use the NMR machine are too lazy to refill the paper in the printer. This leaves me, poor little undergrad, to run downstairs (3 flights) to the office to get the key to get more paper. Then when I finally get the printer working, it doesn't print out the ever important first page that I always need. (And you can't get it to print out again.) Aarg. I think those grad students do these things on purpose.
