Clump

So I board the subway and see a seat
 Dart across the aisle
Clump down perhaps a bit hard
Young guy next to me glares
At the last stop I get up
He sticks out his foot to trip me
As he exits I wait on the platform
Make eye contact
Anything can happen
He could have a knife
Then again,I could be crazy
In that moment
I realize a single trip in this city
Could change my life
