Evanescence

Perpetually lost in the pell-mell of our minds,
transient lives become them.
Akin to a lightning flash,
they awe-inspire one moment
and fork into a shadowy void in the next.
Leaving you with marvel and regret,
they are the second chance you never get.
The best poems are the ones you write in your head.
Unfortunately, you have to read this one instead.
