Me. On the Internet I usually am talkative - you'll rarely hear me talking as much as I can write within a post here on PC. But even there I sometimes feel like a retard because of my tendency to ask/bring into conversation totally off topic things. This reminds me of someone I 'know' (on the Internet of course) who does that, only that he is kinda dumb.

Sometimes I am amazed how talkative I get irl, even though it's 99% random things I talk. And yes, I feel retarded afterwards.
There's a person I feel I can comfortably talk with, but the question is 'can I really do that?'. Sometimes I wish not to be able anymore to 'feel' when someone is annoyed/bored by me, perhaps that way I won't feel retarded anymore...nah, I still would.
