Cockeye, I am normally the same way. Especially with the fly fisherman, I have only been fishing the Clinch for maybe a year so I feel like I can always learn something from someone else. I can also talk to a brick wall so having people closer to me isn't that big of an issue, it's just the way both of these guys acted as they jumped in beside me.
I have to say I have encountered way more people that are friendly and helpful than not. (It would have helped if I was actually catching a lot more but I was struggling myself when I felt like I should have been on the fish.) It happens.
