Raindrops

“I can see some black circles.”

“I can see some white circles.”

“I can’t see some circles. They’s half of circles.”

“Yes, I can see semi-circles too. That’s what we call a half-circle. But I know that the rest of the circle is there; I just can’t see it because of the reflection in the puddle. Shall we see if I’m right?”

“It’s stopped raining.”
