Jason, what have you done to try to get in with the group bowling? I mean, what have you done NOW while everyone is bowling?
Have you said hello, listened a moment and then asked a question or made a comment to show that you are interested in whatever it is they are talking about? That is the best way to start off and get involved. Focus on them ,show interest, listen more than you talk, etc.
I notice in your posting history that, at least in your online life, you don;t tend to show interest n what others are "talking" (posting) about. In the first couple of pages of past posts, only ONE was on someone else's thread. Everything else was a thread you started.
Maybe you just need to work on joining the conversation already in progress and not on turning the conversation into what you wish to talk about.
That can be a difficult social skill for someone to master--and may be related to the competitiveness. on some level driving the topic could be a competition for you too.
If you have not tried that (showing interst in what the yare talking about and listening at least 75% of the time to only 25% or elss talking), why don't you put your phone away and try that now? Hopefully it will get you somewhere
