It's a dangerous place out there, among the rips and sharks, especially if you are a poor swimmer. But this is summer. We are expected to be foolish and carefree. Too much sun, too much food, swim out a little further each time, catch a bigger wave, swim outside the flags, occasionally staring back at the shore to see if anyone is noticing how brave you are. Risk is part of summer, of feeling good about yourself, of learning, of growing up and being just that much better that your little brother or keeping up with your big brother. After all, we are all protected by a flapping yellow and red cloth on a stick.
