Jealous?

I'm not quite sure how you leapt
to the conceited conclusion you did
but I've never been known to envy an inept
self-delusional kid

I've got much more experience
and it seems a bit more skill
while all you are is a bad expense,
an ever growing bill

not to mention how they're up your ass
every second of the day
when my shift's done I let it pass
and simply walk away.
