learning how to think

Sometimes I feel insulted that D seems to have so little respect for my well-trained mind. But why? He's excited about what he's reading and wants to talk to me about it. Can't I just enjoy his engagement with whomever or whatever, even if I'm not in sync with his way of thinking? I am trying to become a person who doesn't take things personally. It's a difficult long-term project for a hypersensitive person like me, but I think it's worth the effort.
