Hand Sanitizer

B has been sick so we're at the doctor's office. When we got to the exam room, April got some hand sanitizer for him. I suggested he also put it on the toy train he brought. He was a bit distraught because it didn't evaporate from the train like it does hands. A few minutes later, he pointed to the sign saying, "Do you see that picture? It just shows hands! It doesn't show toy trains. You should've read the sign and not put it on my train."
