My son was asking about what our turtle thought of us, as the turtle frantically begged for food from inside its aquarium. "Can you imagine," he asked, "that beyond this barrier you can't cross, there are these magical beings who can fetch for you what you really want and bring it to you across the barrier?"
"I don't need to imagine that," I replied.
"I have just such beings in my life."
"Yes. They are called bartenders."
