Best Friends?

What are best friends?
Are they always there for you?
Do they keep secrets?
Do they hide from you?

Do they stay by your side?
Or do they trash you to your enemies?
Do they comfort you in tough times?
Or do they make fun of you like you have fleas?

Do they pretend they care?
Do they stab you in the back?
Do they actually care?
Or do they use you?

I don't know what a best friend is
Because I thought I had one
But it turns out,
She makes me feel like a fool.

I defended her in school
When everyone else made fun
I hung out with her
Even if it meant not being cool.

After everything I do
She ends up taking advantage of me
Now she barely confides in me
Or even consider me a best friend.

She has kicked me out of her life
Now I'm just another person that goes to school with her.
She is liked at school now,
With friends galore,
But she has kicked out the one
Who loved her for her.

So tell me,
Is this what "best friends" do?
Because if it is
I would rather not have one,
I wouldn't want to hurt you.
