Embarrasing moment

One day I was taking a walk on the beach and stopped to look at the waves. Suddenly, Ithought I saw something struggling in the water. It looked like a man who was having trouble swimming. At that moment I reached for my glasses, and then remembered I'd left them at home. I couldn't see the object clearly. Just then a big wave came, and the man was gone. At that moment I ran as fast as I could to get the lifeguard. After that we arrived back at the spot where I had seen the man. When the lifeguard looked through his binoculars He saidhe didn't see a thing. I was pretty embarrased. The next day I bought a newspaper. There was an article about dolphins swimming near the shore. As soon as I read the article I realized that i had seen a dolphin in the water - not a man!. After that I never went anywhere without my glasses again.
