Our typical office hours are 8 a.m. to 5 p.m., or 40 hours a week.  However, I come in early (usually by 7:30 a.m.) and often take shorter lunches.  Right now, I'm averaging 43+ hours a week. 

I usually don't take work home with me (in an emotional/mental way) unless something happened that really upset me or excited me.  Very rarely, I have taken things home that had to be typed and were on tight deadlines (if we have several projects with a similar deadline). 

Overall, I enjoy my job and co-workers, and feel blessed to work for a great company!
