Teen bullying

Pete you're a piece of shit
You're a disappointment 
Out of everyone its you I hate 
Hurry up son you're gonna be late 

Pete where is your homework?
You didn't do it again?
You'll stay dumb forever
Class look at an example of a failure

Pete you'll never make the cut
You'll never measure up
You might as well quit 
Go to the bench and sit 

Pete did you hear about the party?
Oh, awkward you weren't invited
Have fun imagining me and you
Hey dumb ass nobody likes you

How could he leave like that?
He didn't even say goodbye 
What put him through such strife?
What made him decide to take his life?
