There’s more than one kind of line, right?

Most definitely! How do you reckon all these lines were made?



“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.”
