I Hate It When...

I go to the gym,
Set my water bottle down,
Come back later,
Take a big swig,
And it tastes funny, kind of sweaty/salty.

I glance around,
A few feet away,
I see another water bottle,
Identical to mine.

Cough,
Choke,
Spit.

I look around.
I'm really not interested
In sharing my water bottle with anyone I see.

I wonder if the matching water bottle owner thinks I just drank from "his" water bottle.
