Speaking according to the situation effectively and justly is like that neat tetris game expert.  People love those who can effectively choose contents to talk.. there are a thousand contents that can be spoken but the shape of which, that can be fitted over the present condition in a conversation is the most welcome. That which is frequently unfitting the present tetris matrix, those people will be avoided,  atleast,  mentally,  by anyone regardless of whatever intellectual differences between these conversees..
