Great thread, Chef. I definitely love the, "You didn't ride today, did you?" I also like cleaning my bike off after a dirty commute and lubing the driveshaft. Keeping that simple machine in good condition can be laborious, but I like being able to do it and it costs a lot less than my mechanic charges me to do the same thing for my car.
I'm not much of a mechanic now, but I'm learning more all the time. I like that.
