My wife doesn't like lightnings. When she was young her mother was afraid of them, and when there was an electric storm he ordered my wife and her brothers to hide in the cellar. If the storm happened at night she awoke and took them to the cellar. Nowadays neither my wife nor her brothers like lightnings.  My mother didn't like lightnings either, but when my brother and I were young, she worried about we didn't discovered her fear. That's why neither me nor my brother are afraid of lightnings. Obviously we must be care to not transmit our fears to our children. Thank you!
