Hi, this is my first post.
I too have no friends. It's been that way for a long time. Since high school. I'm 26.
I've had many opportunities to make friends in instances where I was part of a group of people that were strangers to each other. Sometimes I have tried, and failed, other times just observed.
Even though I know they are strangers, it always seems that after 5 - 10 minutes they all know each other - to the point you'd think they always knew each other.
I never survive further than that first awkward 5 minutes of introductions.
Other people always seem to have something to talk about, something in common. That thing is their friends. They talk about what they did with their friends or their friend's friend. They get frequent exposure to meeting new people (friend's of friends etc), but they aren't alone when they do it.
I don't have that. It makes it as near impossible to make friends as it would be to open a savings account if you have to deposit at least 100k.
