Trust me it's not just wives. I have had employers that were like this as well.
I was an IT administrator for a number of years. That started out as a PC support guy that did network infrastructure, phone system support, printer repair and support. I also took care of about everything else that had electric going to it. I even made the mistake one day of helping a maintenance guy weld a broken hinge on a dock plate. When they found out I could weld in the maintenance shop I got to do a lot of that. Point is that anything that you are good at, folks will ask you to do.
I can say honestly that other than tires and oil changes, I do all my own car repair. Which may not sound like much, but I have rebuilt several engines, installed numerous cams, heads, intakes and had a number of people bringing me their hot rod cars for everything from carb tuning to engine swaps.
My only saving grace with my new hobby is you can't legally gunsmith for others unless you have a license. So I may get a break there.
