Flash Poetry: “Stopping a Freight Train”

Why can I not stop thinking
about you and all the things you’ve done?
Why do I expect more from you
When the past has proven your mettle?
It’s like trying to stop a freight train
with shaving cream
or home-concocted slime
Too poor and porous
For this use.
Arguments played out
in my head alone
Seeking answers
Of only meeting partway
Over-analyzing
you every move
a chess game
and I’m the only one playing.
