I imagine many of us get this reaction. It's actually a principal reason why I sell on eBay - my wife can't complain at anything I keep (or pick up from you guys or the bay) if I'm net positive, which I am by a descent margin. I also placate by saying it's merely fun money for babysitting, etc. and that seems to work. I just have to ensure that she doesnt start to see it is income, and thus want to save it or use it for the mundane.
Oh, and awesome outfit!
I'm afraid that this might be the story of most of us here...every once in a while my thrifting has to fund a household purchase to keep the wife off my back about the time I spend on clothes or the piles of packages going in and out.
