I am starting this thread in the hope people will please share experiences and insights into how they have developed friendships in nature adulthood.

In my experience it gets harder as we age and many people are already in established friendship groups and not necessarily open to new friends (although they may like the person).

I am not talking about how to meet people but rather how we develop those friendships - this is actually the bit I find difficult so in the past I have had acquaintances but not friends really. I am working on this and trying to develop new friendships but it's not always easy.

Thoughts?
