Levi's and T-shirt, on the clean side, is my favored battle gear, but I do have a quirk that I wonder if I share with anyone......
Before I start any work on my cars, I must absolutely feel clean. If its a Saturday morning, and I've rolled out of bed feeling a little greasy or smelly from the night before, I gotta take a shower before I can feel comfortable and competent wrenching around on my back in the driveway. No telling what my wife makes of this, especially when she brings out a lunch-time sandwich and I'll eat it with whichever hand isn't holding a grimey ratchet!
