After toddler storytime, we joined Alanah and some other kids at Polo Park. The girls couldn't stop laughing and smiling and coating themselves in dirt. And there was no biting. The party ended when one of the other moms found a giant knife hidden in a tree. No lie. And the park is next to an elementary school, and kids are there all day. And now we know what those kids are up to: hiding giant knives in trees.
