A Backstabbing Best Friend

Why do you love to hate me?
Why can't you let it go?
After all of these years that we spent
I've decided it's time you should know
That everyone talks crap about you
That nobody even cares
That when you're turned around
Everyone gives you a glare
Nobody wants to confront you
But it isn't because we're afraid
They'd rather you seem and act stupid
And partake in our vile masquerade
Please don't assume that we're vicious
Oh no, on the contrary
You are the only outsider
What? You don't believe me?
That girl, over there thinks you're rude
Have no sense of appretiation
And he says that you're just a bore
Could put to sleep the entire nation
That group in the corner knows best
And said that you're out of your mind
I think that you know the rest
'Cause what I want to say's quite unkind
I didn't mean to offend
And who really cares what they think?
Remember, I'm your best friend
*As I turn to someone else and wink*
