Working on a Saturday?

I'm off for a full day with the marching band. I find myself exhausted and wish that I could go home at the end of the day and have my weekends off. Shouldn't I be excited for my extra curriculars? At the very least, I shouldn't dread them. Right now I live 45 minutes from my school. Maybe if I lived closer it wouldn't seem like such a big deal to drive over there. I actually had a dream last night that I was working at an elementary school and got to go home at 3 everyday. Is this a bad sign????
