why do i feel that way?

why do i feel a loner everywhere i go? from sec sch to church to poly. yeah, i have great friends who i can to anytime, i have great friends who share joys and sorrows with me together, i have great friends who know what i like and wad i would do and vice versa. but seriously? its like today again, i sit down there listening, and i feel left out. and it happens nearly weekly. sometimes i feel like i can get along very well with someone, on other days it feels really outta place. sianz lar.....
