Contextual Analysis of "pacing the floor" in Lyrics

snapping my fingers

i sulk in my lonely room as i lay my weary head

i know it's you that i'll find

i know that i'm bored

long time

i've been watching the door

and i'll have all this room

sick of it all

my mother will start to worry

so

heard a knock on my door

waiting for them

rest those tired eyes and vacant mind

outside your cellar door
