Everyday you stalk me

[Achebe]

This is a work in progress, and I would love to hear all feedback on it. 

Everyday you stalk me
and with goofy faces
you like to mock me.
I try to reason to no end,
as all you do is imitate me again
and my only revenge 
is to tell all my friends
that man in the mirror
is a real asshole.

Lines 1-3 set up nicely with the last 2 lines.
the rest of the poem is pure filler. I find it unrealistic that you try to 'reason' with your reflection, so lines 4 and 5 make no sense to me.
If you really 'tell your friends' - the assumption being that you didn't use 'friends' just to make that line rhyme with 'end', that your reflection is an asshole, it doesn't come across as particularly clever, which detracts from the twist at the end, a clear attempt at being clever.
