How to recognise a ''wannabe'' ?

i have come across a lot of people, trying so hard to act all cool or all smart and sophisticated and pretending to be that perfect thing with the perfect life and the perfect friends ... Me, on the other hand, keep making mistakes, i have never been politically correct and never ever fit into any damn group.... Most people tell me i am just ''different'' ... People tell me that everything about me is different ... Well whatever that means .... I am called intelligent and yes of course, i am very open and straightforward and have never believed in following or supporting things i just don't belive in .... But there is no particular genre i belong to .... Things like nail polish or guys dont interest me .... Well am 23 now .... And well, i find it stupid.... The way most people converse ... I find it fake and superficial .... Id rather people jus be themselves, not afraid to make mistakes and not ashamed to wear an outdated dress if it suits them ... I find most people ''wannabes'' esp since am an oddball myself and today.... I am kinda sad at the pathetic way i dont belong anywhere .... Well i love people, no issues but i keep wondering, is it me ? Or is it them ? Maybe i am the problem after all .....
