My husband is a laundry freak. He does it all. However, if I was missing I don't think he would think to do it at all. Laundry would be the last thing on his mind. Remember Scotty was out putting up flyers and such. I don't find the fact that he let the laundry go bizarre at all given the fact that most men don't do the laundry.
I agree that he was "busy"(and he did quite a bit of golfing during that time), but were talking about 2 months here...and for the blouse to go from the hamper to wadded up and stuffed in a drawer is strange to me.
