What are the best (or worst) parts of your job?

Tagging along from one of the previous posts about people's jobs, what are your favorite things about your job. If you can't think of anything, then what are your least favorite things about it or what do you think you'd like to do instead if you could?

My favorite thing is the appreciation we get from passerby. I've never had a job where people are genuinely appreciative of what we are doing, and it's nice to get that feedback from people even though the work itself can be pretty difficult. If there wasn't that for my job, it would certainly be less rewarding.
