I hate when people (falsely) claim I appear uncomfortable in social groups.

I don't even know what that means exactly, but it's certainly not true. More than 1 person has told me this recently and the thing is I don't even actively socialize with them. I mean maybe I do have a trace of social anxiety, but I don't really think so. But, "being uncomfortable" is literally out of left field. I couldn't believe this was being hurled at me.
