four walls

 

lying

thinking in the dark

 

four walls do not

make a room

 

a room needs a floor

and ceiling

 

four walls

a ceiling

and a floor

 

four walls with no door

can keep others out

but keep you in

 

a door

an invitation in

or

an exit out

 

try to decide

which is best

 

door or

no door

 

or roll over

and go back to sleep
