I'm a shy guy & have very few friends. My problem is that if I think I'm your friend, then just ask for anything & I'll try to help/do/find/whatever - 100% invested.
Difficulty is that I'm also naive as hell & most people can't/won't/don't feel the same. Once I've been disappointed, I walk away - hence the few friends part.
I actually don't mind not having an active social life (I'm mid 50's
S, I'm comfortable just being alone or with Mrs. O), but I still get hurt when I let my guard down & the cycle repeats itself. The guard gets let down less and less as the years whip past.
That's all - I just needed to vent.
