I've been trying to do this. Even practicing in the mirror, but it doesn't feel the least natural. Like I still don't know the rules or limits. I feel like a bad actor playing a bad part who doesn't know his lines. Everyone else seems to do it without a thought. I used to think everyone just thought stuff up more quickly.

The friends I have came to know talking comes later. Mainly from a situation where we were around each other enough to get past my weird quiet stage.
