You're doing fine. I think there's need to be potential for friendship in the first place. If one person don't get the other's humour or the other person don't get the response, I think it could be because there's not enough shared experience or shared perspectives for the two people involved, and that's that. There's nothing you need to do - the kind of person you are, will likely be friends with, the kind of people, your kind of person tends to be friends with, so enjoy. :)

understood. though, there are different rules of engagement for potential friends and a bunch of mostly random people with whom you're playing a game. Still, agreed, there may be place for offense. And offense can enter even without an invitation.
