That fun game is usually followed by the kids walking, dripping wet, into the house and tracking mud all over my floors just so they can get something really important like a plastic dinosaur they can throw down the slide repeatedly until they get bored and they whip it on the roof of the house.
Another fun game they play entails throwing a basketball as hard as they can at each other. This is followed by two or more kids running into the house and crying about their injuries. Finally, the famous who started it conversation begins.
They also play a great game wherein the dump out every bin of toys, skates, baseballs, mitts, and water guns onto the garage floor. The toys must be left there for at least 72 hours.
One of my favorite games they play is Extreme Catch. One person stands in the front of the house and one stands in the back. They lob a baseball back and forth over the roof of the house to each other. Fun.
Another game uses a bag of pretzels, some dishes from the house, a piece of leftover pizza, a doll, a toy camera, the case from a Barbie DVD, and some dental floss. I'm not really sure what they do with these items and how they use them in the game, but I'm sure that every one of these things is an important component of the game. I think the object is to make sure all the items end up in the sandbox.
I can't wait until school's out so they can stay outside making up games ALL. DAY. LONG.
