That has been me in the past. Not to my wife, but as a younger person, I only read history books and stuff (still do) and felt superior because I did that (I don't do that anymore of course), so I would sneer at my friends' fiction and stuff because it was "worthless" compared to "real history" where you "actually learned stuff".
It's a dumb mindset, and I definitely don't feel like that anymore. I still don't read fiction or enjoy it, but it's just a hobby like any other, or like my thing with history.
