I'm officially jealous of your weather - it's about the same temperature here, and it sure isn't going to get any hotter! Our hottest summer days just barely get into low 30s. I think I'll just console myself with the thought that temps in the 40s are too hot to do anything. Expect snide remarks if you ever complain about the heat ;-)
Oh, and I forgot to mention that we pay someone to come in and clean our bathroom once a week. David suggested it when the twins were tiny and I literally couldn't find the time to do it. Of course once the twins were a little bigger and napping regularly I very quickly decided that if I did have the time I could think of plenty of ways I'd rather spend it than cleaning the bathroom. He is quite happy to keep it going, so who am I to argue?
I do make a distinction between mess and dirt though. Untidyness I can live with. Grime is another story!
