My wife works 18 on 18 off at hospital, and I travel at least three times a month, so I don't normally need any excuse. But I have used the Home Depot excuse in the past. That one is usually golden. She would never want to join me, and I can come home with nothing and she wouldn't even think twice. She may get snoopy when I'm always wearing my mongering uniform to go to HD, but oh well we cross that bridge when we get there, da?
