Until you actually own a house and learn by making mistakes, no one truly knows DIY tasks all that well. I'm not too bad at most tasks, although anything above very basic electrical and plumbing repairs makes me nervous. If I screw up a brick patio, I can fix it. When I burn down the house because of faulty wiring, that's another story...
This is true of my son. He once told me he was taking his fuel-injected car into the shop to get his carburators adjusted.
I haven't read all the thread and someone may have mentioned this. This also applies to BB, Gen X and Y women as well - - basic cooking skills (cooking from scratch), basic sewing (how to mend a hem or sew on a button), basic gardening (raising veggies), little things on how to bake bread from scratch, basic first aid, and small repairs around the house (patching with plaster, how to fix a too-big screw hole), etc. Just basic "survival skills" stuff.
My mom, 84, brought her own toolkit to the marriage. Good thing, too. My dad was a total dunce when it came to any kind of home repair. He's been gone a couple of years, but she still laughs that she has to turn the kitchen switch to the "off" position to turn on the overhead light as dear ol' dad installed it upsidedown - -
-"I will repair what your husband fixed."-
Exactly! My sister thinks she can install ceiling fans, so what we're left with are ceiling fans you can only set at low speed because a higher speed makes them wobble all over the place.
Same with autos.
