When I got home about three hours having left work (it is normally a 20 minute trip) I was pretty tense.

I was irritated when the boys decided to pretend they were sleeping and didn't help bring in the groceries or acknowledge I was home. 

I needed some time.  A break.  Tough to get with these boys so...since they were pretending to be sleeping.  I just let them pretend and went upstairs and hung out for a while.
