My uncle was the biology professor. When I was young he was used to take me to the biology lab, when I saw pigs, cats and other animals. My uncle also influenced me through nature walks. He often takes me for a walk in the backyard. We would catch frogs and snake, and find fireflies in the sky. He seemed know everything about wildlife. Eighteen years later, think about my uncle and her influence on my life, I feel very lucky. I am grateful that I got the chance to learn for him. He helped me develop my interest in all that was alive and sometimes death around me.
