I agree that hams tend to be obsessed about their antennas and radio (I'm certainly guilty, but it's just who I am). No different than our spouses who just care that the car starts and the A/C works and could care less about suspensions and dual transfer cases. It's a hobby in and of itself. Big part of the reason we delve into it daily is so that when you actually might count on it to work you know that it will or how to fix it.
OTOH, those guys on the 145.145 repeater are friends and they are just talking about the same stuff they would talk about over coffee. We are no different, you don't have to talk about your doctor visits and ham towers necessarily and trust me hams get to recognize your call sign and when you call out they will know 'Hey, you're those Toyota guys.' and probably want to chat about it.
