People in my life

well i have many people in my life..which is good...at times. i am in no way a social butterfly i am most comfortable in my own little world .... but when i do socialize i am genuinely genuine...when i c ppl judging others behind their backs and being totally normal infact friendly on their faces i loose trust in them....recently this is all what i have been seeing in ppl...ppl i geneunily care about....do they talk about me like this behind my back too? i guess they do...y not! y am i different? i know i am not..... ppl judge ...on small attributes small instances ..things that happen to the best of us....i loose respect for them....i loose trust in them...and my problem is i am not fake...i cant be...ppl come n go...but the only ones who stay in ur life are the only ones that matter....
