Help you...help me

Its amazing how ppl hide selfishness and their meanness behind a cheerful boisterous exterior. If their manner is a little too condescending a little to matronly, u can guess they are being mean. People acting in that superior yet indulgent manner, as if you were a child, really get on my nerves. Pretending that we know nothing and what they say is gospel. This is a way of getting their own way. They act like ur a bufoon and dont know what ur doing, yet they are willing to help you and show you how to do things right. This is only to hide the selfishness they have within. You must have experienced it....go out with some friends and when you come back at the end of the day you realise that you didnt do one thing that you wanted to do, didnt get to have your way even once and yet they made u end up feeling like you were the hindrance. Or soemtimes you ask them something, you give them two options --- if it benifits them they are willing to suggest the riskier one. They make the decision in a cold calculating manner judging whats best for them and not for you. Let me give you an example --- you arrive late and reach the classroom doors. You peek in and catch your friends eye. The teacher is already in. The teacher may be very strict and wont take kindly to your intruding and disrupting the class. Still if your friend is sitting alone or getting bored he will wave you in "cmon in, its no big deal, the teacher wont mind". At this juncture the friend wont choose whats right for you but whats right or rather convinient for him. Even at his friends, i.e. ur risk.
Its very difficult to recognise these situations, but if you know what to look for its pretty easy. But then getting out of these situations is harder. Specially if ur not the assertive type.
