Is this a friend?

Some times we can be as close as sisters.
Then I say something and you hate me the rest of the day.
Tomorrow we'll be touchie.
Then the next day best friends again.
We'll walk down the halls happy as can be,
passing notes in class and in between.
You run to me when your scared,
I help you, then you hate me.
How can I be a good friend, when you think we get to close You have to be so rude just to keep us apart.
Then a little while later tell me why and its usually my fault.
How is this being a friend?
How can i be your friend when you don't trust me.
I wont hurt you like others have and will.
But still I think you hate me for being your friend.
But how can I not be,you've helped me,
so why can't i help you.
How is this being a friend?
so my question to you is are you really my friend?
