I have a good buddy that is like the OPs fishing buddy. He's been that way for 3 decades. It pisses me off at times but instead of losing a hunting buddy, I just put up with it. He's the only buddy I have that would spend 20-30 days in the UP bow/rifle hunting back to back and enjoy it. Tent camping in 2' of snow isn't any of my other buddy's idea of fun. That and he's a good buddy, keeps me from ending my hunts with him. It's not worth it and he's not gonna change. If he's a good buddy and that's all that bothers you about him, consider yourself lucky.
