I just can't talk about something I don't care about -- the weather, what did you do over the weekend (none of your business), etc. Also there is a lot of jockeying for position in conversations, and it drives me nuts when one person keeps interrupting the other person or pulling them off their own topic. But if someone does engage me about something personal, then I'm right there with them, feeling everything they say and sometimes tearing up in the sad parts, and then I'm exhausted because I've been listening so hard. So it's a combination of trying to decipher communication that doesn't mean what its words say, or being 100 involved in communication that does mean something to someone else and feeling connected but after awhile, overwhelmed, and with a need to just sit with it for a bit. Also I can't stand anxiety, if people babble when there's a quiet space, or insist I talk when I have nothing to say and I'm taking a break and doing some people watching, for example, which to me is very entertaining.
