This is one of the things that bugs me most of the time and it really hurts. there are some types of people that are like that , they don't talk to you or don't ask you "how are you " and then boom they need something and all of the sudden they see you .
I had so many friends ! like that , some of them even does not answer you when I'm trying to be nice and ask how they're doing , but when I recieve email from them becasue they wanted to ask me something . how I should react; be cool and helpfull or ignore them like they always do .
I always did the first option because I'm that type of persons that can not ignore others and also can not confront them about their bad behaviour.
but how you can fix that , or how you behave with these kinds of people !?!?
