Well some people sit around and talk about other people. I would recommend avoiding those gossip-y types. Talking about other people always bites you in the butt and trust me those people will talk trash about you the second you are out of ear shot.
Then you have those who like to discuss current events and what is going on in the world. Personally I think there is enough of that depressing and anxiety triggering nonsense on the news channels ALL DAY LONG.
I like to hang out with people who share ideas and talk about how things were back in the "good ol' days" when life didn't move at the speed of light. I enjoy people who can hold a conversation without having to belittle someone else or complain about the current state of the government. Its been my experience that the kind of people I like, are not what society considers "normal." but that's okay because neither am I. And I like my anxiety-riddedn self just the way that I am.
I have rambled a lot but my real point is you gotta put yourself out there in order to learn how to have those awkward comvos. Ome of the greatest Hockey players in my life time - Wayne Gretzky- said it like this: "You will always miss 100% 0f the shots you did not take." So get out there and take some chances. You might stumble along the way or you might find your people...you will never know unless you take that shot.
