Extroverts

I'm fucking sick of them. If my body language and speech give obvious hints that I'm not in to mood to chat, can't you pick up on the message and leave me alone? I can usually tolerate you talking about everything that you can possibly talk about, but sometimes it gets to be too much and I can't take it anymore. I'm sick of it. And then after you try and make conversation and I ignore everything you say, what compels you to continue? I don't get it.
