There's something to be said for not burdening others with your own problems in inappropriate situations, and/or out of respect for their own problems or lack of interest/ability to meet you halfway. But, of course, at the same time, the insane sort of macho ideal Mistersloane referred to where repressing any conversational sense of your own subjectivity as an "emotional" or "psychological" being is completely ridiculous and immature.
I also agree with whoever said that it can be reverse self-flattery to assume that your own "deepest darkest" secrets or "self" or "emotions" are sooo special that it would be simply shocking or overwhelming for others if you shared them. Oh please! People may be different, but we all operate according to a handful of very similar and basic motivations in the end. I have no time for people who, say, think it's a huge deal to talk about personal life issues in a goddamned chatroom or message board, especially when it's a truly anonymous situation.
As if it's written in stone once you press "submit" or something and the Big Other is watching and is going to punish you for talking about your own inner reality.
So paternalistic and weird to me.
