I serve a drink to those I believe are worthy of receiving.

As much as I deem myself as pretty particular on deciding who can drink it,

I am often left wondering if my criteria are proper.

You see, my drink comes from a bottomless bottle, or so I thought.

The selected drink to their fill.

Once they are satisfied; they leave.

Vanishing into thin air.

Leaving only the residue of their saliva

from when they were using my cup

The unselected do not leave

They knock and knock and knock

hoping to drink from this bottle of mine

“Psshhhtt”

I open the bottle

hesitant and uncertain

“Should I pour him a drink?”
