While I assume you are an instructor, what makes you think you are supposed to work on a vacation week????? HUH?
I do see the need for having advanced lesson plans. Can't you give in class assignments while you grade? I was never one to expect the instructor to continue working during all "free" time.
I think you did some good stuff (I have my origami stuff waiting...on my hands mostly

) and I hope you had fun. Now don't beat yourself up over it.
Time's a wastin! Schedule your necessary activities into what time you have this week, and be good with it. Besides, it's not like you have to take the clothes to the creek and rap them on rocks
TC!!!
