BOTTLE CAPS IN THE GRASS

When I walk I look down
Not at my phone always
But at the ground. 

At the park
On the grass
On the hill
Facing the sun
There are 
Strewn about 
Caps to bottles that aren't around. 

What good times must have been had here
Park drinking.
Last night or the night before
Summer was made for this
I think, past tense.

I pick up one of the caps.
It has a 10 on it.
Imagine 10 caps. 10 beers. 
I used to think
I could drink 10 beers in one sitting
But now I no longer do.
