I am pretty introverted but over the years I have accumulated a large set of friends. I don’t call all of them at once. But I do sets of 6-10 at a time.
I won’t go to a bar or a club alone. I don’t like it. But a good set of friends in a familiar location like my house (or theirs) makes for a really good time. We definitely try to get together at least once every couple of months.
