Absolutely a missed opportunity! I love reading and the first thing I would ask if I saw my date with a book would be about that book! Then I get to bore them about all of the philosophy I read lol
But seriously, I’m a sapiophile and I need my romantic interests to be interesting. I see intelligence in many different aspects, so I’m always probing and looking for intelligence, even if my date/friend/colleague can’t see it in themselves.
