Caroline: Mama, do spiders cry?
Mama: Uh, no, I don't think they do.
Daddy: No, they don't have tear ducts, so they can't cry.
Caroline: But what if one of their friend spiders die? How do they express being sad?
Daddy: Hm, well, not with tears. Probably some other way.
Mama: Yes, I bet they do a special spider dance of sadness.
Caroline: You're wrong.
