Yuck!

Yuck! Adults kiss each other on the mouth, and children find it disgusting! What’s more, you can see it from afar: when people are about to kiss, their lips become all pink and shiny. Little Léo makes jokes about it, as do the other kids at the summer camp. But he has a secret he won’t tell his friends: his own mouth has actually begun glistening. And, in reality, Léo desperately wants to give kissing a try.
