I never had the comfort zone issue, or any fear of approaching and talking to people. If anything, for me it is the skill. All the people I know depend on ongoing conversation and I can’t provide that because my mind does not have that skill (and this is inherent), so I don’t meet their cost requirement to make friends with them in any de facto way. If people were open to being silent with others and let the activities do the talking, that would be one thing, but that’s not how it is.
