Narrate the childhood experience of Douglas.

William Douglas wanted to learn swimming. He went to YMCA pool as it was safe. But an eighteen years old came and tossed Douglas into the deep end of the pool. He was frightened but planned a strategy. He decided that the moment his feet hit the bottom, he would make a big jump, come to the surface, lie flat on it and paddle to the edge of the pool. However, because of too much depth, Douglas could not resurface. He tried more than a couple of times. He tried to yell, but no sound came out of his mouth.
