I am not sure what you want. A day with my wife who had little interest in old tractors at the county fair, looking at old tractors. When suddenly she began discussing the differences between the Massey Ferguson and the Olivers. Some shock when I realized she had read up on them, not because it interested her, but instead because it interested me. All I could do to reciprocate was to read up on music forms she liked to play and the kind of paintings she liked. So I could discuss with her and her friends the difference between Art Nouveau and Impressionist or Cubism without sounding like an idiot.
A durn good marriage I think..
