I met my wife because of a pinball machine, F-14 to be exact, and for the first several years she was rally into it, went with me to auctions, roadtrips to shows, even helped me clean playfields etc. However she never had the kind of obsession for it that I do, and eventually she dropped away from it entirely, but has always been supportive, and more importantly tolerant of all the time I spend on it, which is A LOT!!
Best illustration I can give of how great she has been, is she didn't say a negative word when I decided to take the money from a property that we sold, take out a LOC against our house, and buy a building to house my collection, pretty special I think!!
