I think he meant that his wife thought HE had a strange hobby and this is someone elses hobby....I think this is someone elses, probably a 'local' hobbyist groups "museum"

I Found a YouTube clip from a German museum and that is amazing. (I have a Marklin HO scale set on a 2m x 1m plywood in the basement, waiting for my grandchildren.)
