When I was a kid (about 14 years old) we were playing with a few friends in a lake nearby. After a few hours of fun, I saw one of our friends popping up and down in the water and splashing the water with the hands. He was at no more than 3 meters from the shore and if he stayed on his toes he would've had his mouth above the water. I firstly thought he was messing with us, but I jumped in the lake for him after about 10 seconds. There was no joke - he didn't knew how to swim and he was in real big troubles. Now, I don't think he would've really drowned in that shallow water, but I'm glad I jumped and I hadn't find out if he would have been able to make it by himself.
