i hate unsaid expectations

need i say more? but i still will since i have to give vent somewhere...
i hate it when X, Y or Z have expectations but do not state it... most of the times, we homo sapiens, the king of animals that we are, with sharply honed social skills, decipher the unsaid ones since our mind constantly measures the space that we get or give to each other... but there are some experts (i call them social crooks) who put on a sham board saying, "I have no expectations", but either go behind the back to complain or communicate it with attitude, saying, "I expected something different."
i routinely land up in problems with such people... since i am a big votary of the spoken word, said clearly, when you make out that i am not able to get what you are trying to say...
i do it... when i understand that someone is regularly goofing up on my expectations, i speak my mind... it makes things easier for me and the person in question, rather than have two people sulk and squirm...
but many would rather do just that than speaking clearly...
possibly, that is the reason why i come across as harsh, tough, heavyweight (which i am)... i say what i have to, not a very wise thing always, but cannot change myself now...
