I don't know either

I don't really understand YOU.

all i could do is saying bye and nothing else.

What i can do is only, cry.
why, why i only know how to cry? i realised that you're the only one who give me advice alway, i realised i need you as my friend. when i message them, they won't reply or won't care, they only care when they need me to help them do something.. I don't know what is true friend, when i tell them something, they won't cares, they only will contact me when they need me to accompany or something else? is this true friend? Why, tell me why. I've try to change ... but ..
