Sunscreen anyone?

Last Friday Nathan had a field trip to the park and enjoyed a picnic lunch. As he was getting dressed that morning Nathan said that he had to make sure he put sunscreen on. I finally asked why and he said that his teacher said that he had to. I told him that he does not need sunscreen because he tans so easily. That the warning to wear sunscreen was for the kids in his class that are pale and not used to the sun. Sure enough, when he gets home Friday, you can see tan lines.
