how to show yourself in a proper way in real life?

Err I disagree. I don't do things in real life that don't fit my behavior. What that is, in my opinion, is people who are fake and/or don't know who they are. I don't do things that aren't myself because I think yourself is just as important as other people. So how to show yourself properly would be to simply, be yourself. And if you annoy or displease others, oh well.

by telling everybody yes,that would not displease anybody.that may be a proper way according to them.

I am me. I act like myself, all the time. I am kind to others, so I'm not intentionally offensive, but anyone who is offended simply by my personality or ideas can just shove off, as far as I'm concerned. :P I think people worry too much about offending others and not enough about being true to themselves. It's true that sometimes someone is going to be upset with you because they don't agree with on something, but as long as you are being polite, that is the other person's problem, not yours.

I just keep to myself most of the time. I don't need to be around people just to worry about making them happy. I have a very small circle of friends who accept me, and leave it at that.
