FITTING IN

When i was younger, i struggled to fit in..... i still have this struggle today. its not that i dont fit in, its just that my personality is not as welcoming as other people. i dont walk into a room and command attention. i dont say quirky and cute things to those i dont know. im just there. if you speak to me i may reply.... or i will just make a little noise to acknowledge your presence. everyone is different. we say that but do we really believe so? then why do we get upset when someone does not respond to us the way we expect? why do we create friends based on their fashion sense and prejudge others who arent as fashionable? if everyone is different, why do we all look the same, sound the same, and do the same things?
