Mathematics
We recently visited Timpanogos Cave. I wanted to be sure I could see all the cave formations, so I brought my glasses to wear on the cave tour. During the tour, Emmett told me that I look different with my glasses on. I said, "I probably look like me, but with glasses, right?" Henry said, "You look like mathematics!" Huh? I said, "I look like I'm a mathematician?" He repeated, "You look like mathematics!" On the hike down, Emmett schooled Henry on the difference between "mathematics" and "mathematicians."
