I don't know about anyone else, but I find it easy to make aquaintences, but I tend to keep a lot of people, including family members, at arm's length. Being somethign of a misanthrope, I an incredibly selective about who I consider close friends.
I find the best way to get people to like you in real life is to be interested in people. And yes, Misanthropes can be interested in people, but just find most of them to be compemtable.
Another thing if found out a long time ago, is that people like to talk, which means they like other people who listen.
I find the best way to get into a conversation with someone is ask them how they are, and show an interest in what they have to say.
the art of smalltalk is a complex but valuable tool in avoiding isolation and getting some decent human contact. Linking one topic to another can be very hard for aspies, from my experience, but it can be done.
I hope this helps you guys
