I can’t swim so I have a strong fear of water. Look back at my childhood, I think that three reasons might explain fear. Firstly, I am not allowed to go near the water when I was a child, as my mother had an unreasonable fear of it. Therefore, I was taught to see to the water as something danger. Secondly, my eyes became bad when I was five. If I took off my glass in the water, I couldn’t see something, and this increased my fear. What’s worse, for a child I once saw a neighbor drowned. Since then I have been more frightening.
