I guess I got lucky. My wife is a trooper. I’ve always been a collector of a lot of things (books, movies, comic books, toys), and she’s been awesome about it. She’s even gotten some of her own things that she used to have on her desk at work (Batman, Nightmare Before Christmas, Kim Possible), before her company was bought out by @$$holes. We bought a new house about 15 months ago, and she let me have the entire finished basement (almost 1/2 the house; has its own bathroom, a small music room that used to be a bedroom, and a large 42 x 15 room is set aside for my Man-Cave.
My parents are in their 70s, and while they don’t begrudge me my hobbies, they would never “waste the money”. I have one buddy who saw my collection, and his only response was “You and I have very different values.”
