Why?

Why Do I put up with being the sidekick?
I'm smart and pretty I think
All you do is tell me that your the better one
Why do I put up with a friend like you?
Why do I never walk away?
I'm a good person
I know I am
I get good grades
I help people
How do I always end up being your friend again?
Why?
Why am I so stupid to keep comming back?
I dont need this anymore
