Every Tuesday, Yotam's grandfather takes him to a coffee shop after kindergarten, where Grandpa Amnon drinks coffee and Yotam likes to draw. One day, Yotam has a question: "Grandpa, what's on your face?" Grandpa Amnon explains that the lines on his face are wrinkles, and they are something that grownups get. He tells Yotam the stories of how he got each of his wrinkles. Some reasons for Grandpa's wrinkles are sad, like when Grandma Dina was sick. But some reasons are happy, like the wrinkle Grandpa got when Yotam was born.
