My dad's 65 or so and he's one of the weirder people I know. He's a little bit like Kevin's dad from The Wonder Years in how opinionated and strict he can be a lot of the time. While he was a good provider in that we never went hungry or without shelter or clothes but he was basically a God fearing version of Al Bundy, largely emotionally disconnected from his wife and kids and working the same shit job putting in a ton of effort not making all that much money simply because it was all he knew how to do. He wasn't that well educated but he's extremely smart and does have a nerdy side that I have to credit for getting me into computers so early. I loved reading Popular Science growing up which he always subscribed to and he bought us a 486 computer in the early 90's when almost no other family at my school had one.
He's also incredibly handy when he wants to be having worked in farming and construction most of his life. About all he likes to do is go fishing and he goes quite often. My mom is in some ways his exact opposite and I'm convinced 99.9% of couples like him would have gotten divorced long ago, but they share a unique cultural story that I think has kept them together. Last Christmas we had something like 30 people there between my folks, siblings, an uncle or two and the grandkids and he spent most of the evening reading a book or surfing the web, like he does during the last half of most family gatherings and I definitely get my introversion from his side.
