I'm like that. One of my wifes friends rides over and they find me outside fixing their bike because something caught my eye that needed attention.
Better story. My brother and I go to a warehouse to look at used motorcycles for him. I am fairly experienced with motorcycles also. Anyway, he picks one out. Complete, but the gas tank, side covers and the clutch cable are uninstalled and one or two other odds and ends. They go in the office to work out the money end and when they come back out I have the bike ready to go. The seller puts some gas in it, it fires up, and my brother rides it home. They are flabergasted and I'm like, "what, it was all just there, I couldn't help it!" Ha ha.
