Growing up, my Dad did almost every repair and upgrade to the cars, house, etc. I'm talking remodelling, car repairs, plumbing, installing appliances, rewiring the house. He build his own central cooling AC. (He put it in the old dog house....don't ask.)
So, I actually, quite literally, thought that plumbers, electricians, handymen, and the like in the movies were a combination of made-up occupations and relics of the "old days".
When I bought my own house and was too tiny and unskilled to do all that my Dad did, I was baffled. People at work ended up telling me there was such a thing as a plumber I could call. And I was thrilled to learn there were handymen!
On the flip side, I did do a lot of stuff myself: Replaced a toilet tank, replaced toilet tank innards, stained many doors and baseboards in preparation for install, repainted my car, refinished my kitchen cabinets, and many other things, myself. Always cleaned my own gutters. I also fixed my car once with a good solid twist-tie :-)
