I know him pretty well. He's ok, I wouldn't call him perfect as he sometimes forgets what he's up to. He runs a small HVAC business and works on airguns in his spare time (ha ha, like there's much of it). He also has some health issues that sometimes keep him from doing things, but he lives with it and moves on. But no complaints there.
I'm sure he didn't mean to snub you and just to be honest, he gets a lot of trade offers and sometimes can't even remember who asked what. He does a lot of tuning and tinkering and doesn't always follow messages well, ... which he should and will endeavor to perservere, and do better.
Lighten up a bit and remember, this is a hobby, it's supposed to be fun.
