You

I don't know why,but i just feel that every time you need me,you'll call me
But when you are happy,You'll throw me away
as far as I can be
I'm not angry......but just really disappointed with you

Maybe you misunderstood my behavior n altitude
I have NO feeling with you,NO MORE
All i want is we can be best friend again
But seemed that it's impossible as my place was substituted by others

PS:What is friendship actually?
