Can You Tell Us Any Unforgettable Event That Happened in Your Childhood?

I am reminded of my VIII Class teacher Shri Sivasubramaniya Iyer. He taught us how birds fly through his lecture and also by showing real life example at the seashore of Rameswaram. It is an unforgettable event which is etched in my memory for ever. It helped me to take up the study of science subject.
