I'm closing the door

I'm going to tell him to stop "dropping by" my office
with his list of 5 questions, "just a minute" while my focus
lies in tatters on the floor, no, I'm putting my foot down,
the delicate one with a sharp heel, I'm not his mother.
and no, I don't owe him, or her, for that matter, the wholesale
transfer of everything I know - no, I don't plan to let him
watch me code, I don't want him snooping in my electronic files,
I've had it, actually, and the door is now closing.
He walks across campus just to find me.  I sit far away
for a reason.  Sorry, the door is closing, bud.
