Going Out With A Blast

The number 3 plays off in pairs
in words, door and floor
3 letters in common
3 that are different

I pace the floor for nearly an hour
then down the stairs to the parlor
where Him watches intently
episode of Crime Scene Investigation

I slip off the gold band from my wedding finger
and simultaneously release the coarser ring
set them quietly behind him like a cup of warm cocoa
Him not the least interested as to what I am fixing

I head for the front door
two letters of o; one an r
Him growls,"Where the F, you think you're going?"
Seconds to count, "House of Sticks go boom."
