Peekaboo! I'm across the street, in an elm tree

Peekaboo! Here I am!
That’s me, with the night vision goggles.
You might call me an appreciative observer
Of your before bed routine
First you brush your hair, then-
 Ha1 Didn’t mean to “show off” with my
Deep knowledge of what you do and
How you do it, but a guy’s got a right to some pride.
