I used to going to the countryside to draw animals and plants. One day I was walking across a field look for rabbits to draw. Losing in thought, I hadn’t noticed a bull to running towards me. About 100 meters ahead was a tree under that I would sit and draw. Suddenly, I heard the noise behind me. I turned and saw the bull. Knowing a bull can run more faster than a man, I quickly reached the tree and climb up. From there I saw the bull kicking my food bag by its feet. It kept done this for 15 minutes and moved away. But I was quite nervous in the tree.
