[Anne]

well i've been friends with them so far 2-3 years.. and i always acted nice with them but i hated them so much..they were very mean to me and would talk bad stuff about me in their language..i kinda understood them cuz they taught me some words in their lang before.. anyways i always thought of staying away from them but i don't know how.. we finished (term 1) and we;re gonna start term 2 tomorow so i thought if i won't talk with them and start my friendship with other girls in my class cuz it's a new year and a new term.. but i'm not sure if they are gonna get mad at me..and make me feel uncomfortable in class.. btw 1'm 14 yr old girl ..any suggestions on how to deal with them..
by the way i unfollowed them on twitter and unfriended them on fb..so they started to sms me and bbming me why i did that..but i just ignored them.. i'm kinda woried to face them
