The Trajectory of a Life

The storyline depends

on the words once said

or the words swallowed

The plot cannot subsist

on what might have been

It deals in a concrete landscape

where each character moves

according to the unspooling

of a script dependent

on the words and actions of yesterday,

No erasers are issued

No going backward to insert

different lines, other events

And if you're lucky 

you can jump in and add

some new lines

if the author agrees
