Yes, I can be rather long-winded and share a lot of what I'm thinking. (Though, as a side note, I'd like to point out that even if Sereno's post was long, I doubt it was comprehensive of his thoughts - my guess is he worded it carefully so as to keep things fairly concise and make sure the point didn't get lost). But the circumstances need to be right for me to actually just start sharing a lot. And I'm not sure an extrovert "pushing" me will do it all the time. For one thing, I don't instinctively like to be pushed to do things, even if it isn't intentional. For another, if someone pushes for my thoughts on something, I'll try to give them what I think they're wanting, not necessarily the full scope of my thoughts. When I really share a lot is when, as Sereno said, I feel it is wanted and not "in the way". Which means room needs to be made, if that makes sense. And sometimes I think that some people feel uncomfortable when there is "room" in a conversation, so they keep talking and pushing to fill in those "gaps". What is nice is when someone indicates and maintains interest, but doesn't try to pry anything from me.
Perhaps you mean "...has brought up..."? I should hate to think I brought about various forms of compartmentalization in you.
*nods* I know the feeling. Both of them.
