"What are these?" She asked me worriedly.
I looked at the dots but they didn't seem terribly disturbing to me. In fact, they looked a little like zits. "I'm not sure, are they hard to the touch and a little painful?"
"Yes!" she replied.
"I'm guessing they're probably whiteheads, Dylan. People get them all the time."
She looked confused. "Whiteheads?"
"Yeah, you know. Zits?"
Sudden understanding dawned on her face. "Wait, whiteheads are white?"
Now it was my turn to be confused. "Yeah. Just like blackheads are black."
Dylan stared at me for several seconds, then with a chagrined "Oh duh, I get it," she grinned at me and returned to her seat.
