Bear with me as I attempt some humor....
Inspired by Scary Mommy's The Moms You Meet At The Pool I've racked my brain and looked around to name some of the Kids You Meet At The Pool. Don't worry if these may apply to your kids. Growing up around the pool I have specific examples of these kids in mind. They all turned into very sweet and responsible teenagers and adults.
Categories are not mutually exclusive. They can also change on a dime, as children often do.
