I can not tell you how many times I get this response when I tell people that I work full time 3 days a week. They always say something like, wow, that's it? THAT's full time? What do you do with all your time off?
What people refuse to understand is that we work for 13-14 hours straight, walk around most of the time, usually stressed out, and then after our shift is completed we have to slip into a deep coma to recover.
