Hi ho, hi ho, off to work I go

Yesterday was my first day of "work" at my father's office. He was generous enough to offer me a "job" volunteering with him and his partner. Since he's a physician and i want to be one too, it's a good opportunity to learn a few things and get a reference or two. And since i'm doing this instead of getting a real job, he's promised to help me out a little more. So that's cool. But somehow yesterday, I got stuck up at the front. Filing. And doing paperwork. That would have been okay...but for 5 hours... i continued to file and pull charts and put them back. Dad got some really exciting stuff...a little skin surgery, a patient that had to be rushed to the hospital...and i was stuck up front, filing away his notes. I found myself falling asleep...it's brainless work, which drives me absolutely beserk. Now i know why i want to be a doctor...so i don't have to file charts all day. Then the lady working at the front desk talks to herself. All the time. I kept thinking she was talking to me. But she never responded when i said "pardon?". I thought i'd go crazy. What do you do to keep yourself sane at work?
