How to be a friend???

To be a friend with other people is not too easy,beacause sometimes it will cheat you, right.

Ok,like one day,you and someone is a best buddy,awayls play togther,eat together,sing together......Then one day,she/he cheat you and say:''I don`t want to be your best buddy anymore.''And how do you feel?Like so sad right.

I remember i have a not really best friend,until one year,she said:I already have a best friend.''I was not sad at all beacause i don`t like her already......

And from that day,i don`t want a best friend anymore.
