Then and Now

I was at a poetry jam yesterday.
Apparently, last week, the topic given was 'drinking'.
I heard it for the first time, and while a few others read their poems, I dashed off mine.
Here it is, written in a few minutes.

It used to be about the substance
About what was within
Alcoholic, or not?
innocence, or sin?

Today, the drink doesn't matter.
When you share the selfie you click
The first question you get asked is:
"Is that straw plastic?"
