I think we make too much of a deal about making friends as adults. Kids are so much easier in this: “Want to be my friend?”, “Sure!”
I’m guilty about this as well, too shy and awkward to just make friends. But I believe most people would be happy to have a new friend if the other made the first move. We’re all just so socially awkward about these things.
Anyway, if anyone wants a friend, I’ll be your friend :)
I realize this doesn’t really answer the question. Best way is to be open and eager to make friends, I suppose?
