Social Anxiety I don't have.
But I do have some good old fashion social awkwardness! Haha well actually hiking has really done a number on that to tell the truth. You meet a lot of people on the trail who are either really socially comfortable and great at meeting new people - or you meet people with more social anxiety or awkwardness than you personally poses and it helps guide you toward better methods.
I have perfect eye-sight, but I have a terrible time putting names to faces! I've met the "usual" MAHHA crew three times already and I have to reintroduce myself to almost everyone every time. I'll remember faces, and what I talked about with those people, and what role they play in the hammock community (enthusiast, cottage vendor, casual on-looker, backpacker, car camper, etc.) but I won't remember their name.
The exception to the rule is folks from the forums I've actually hiked with. Two or three days on the trail and I'll remember your handle. Kinda sad it takes that much, but like a few already said, these folks are friendly and forgiving and they don't let the small stuff bother them.
That all being said, if I reintroduce myself to you, it's not that I don't remember you - I just can't place your name! It's probably on the tip of my tongue too! Apologies in advance
