When Son16 was about 5 years old, he was outside playing on the driveway one warm summer day when he dashed into the house, told his mom, "Don't look out the window, okay?", and then dashed back outside. Now, my wife is a very smart woman. So she did what any smart parent would do. She ran directly to the window, did not pass GO and did not collect $200. And she arrived at the window just in time to watch young Son whip it out and pee all over the driveway!
When you make the decision to have kids there is just no way to predict what types of rules you might have to make up. But 'thou shalt not pee in our yard' has been a standard guideline for our kids since that day.
