actually,i like that word at the above very much !it realised me everything.when i thinked about it carefully,A TRUE FRIEND IS,A FRIEND THAT ALWAYS HELP YOU WHEN IN TROUBLE,AND LISTENING YOUR PROBLEMS..but, the useless friend is,A FRIEND THAT COMES TO YOU JUST ONLY WANT TO JOKE,LAUGH AND ANYTHING,AND ALWAYS RUN ,WHEN WE RE IN TROUBLE...i overheard this words from my brother.he always advise me to have a good friend,not the useless one.i thinked,before this i befriend with wrong person,so i made a decision to stay away from her untill i leave the school.bye bye !
