I can kind of relate to a bunch of that. For example, there's something wrong with the fan/light and I think the receiver for the remote is busted. I can buy a replacement and fix it. My wife's first reaction is we need to buy a new one. I have fixed stuff around the house that normally my wife's specifically her family would call and have someone come over. I've changed my fair share of tires, filters, batterie etc. where her family calls AAA. And it's not always because her family was too good for it, her father had a messed up back and didn't have the best of a father who taught him how to do things. My father taught me a bunch of stuff but I'm not a mechanic/contractor but I can teach myself to do things that I feel are basic. But, now that I'm older, yeah I don't want take either of our cars, put tire ramps under both of them, bring some sort of container, take out the oil plug, drain the oil, replace the oil filter, put in 4 bottles of new oil, take off ramp, dispose of oil. He's right about time vs money trade off.
