Needing firewood, I quickly set out with my best friend, Bruce, to look for a tree to cut down. Cutting down a tree in a snowstorm can be dangerous. So it was important to have a friend who could warn me of dangers.When I chose a big 23-meter-tall tree and prepared to cut it down, Bruce suddenly warned me, “Dont cut down that tree! Its too close to the power line!” I wasnt sure about it. So I decided to disregard his warning. I couldnt wait to finish the job and go back home. I began cutting down the tree. When the tree fell, there was no longer any doubt whether my friend was right.The tree caught the power line, bringing it to the ground. I considered cutting the tree off the line. After all, electricity cant travel through wood. As I reached out my finger to touch the tree, pain ran up my arm and through my head. I had been shocked!After I returned home and told my mother what happened, she quickly called the power company. Workers from the power company soon arrived. One of them asked if I had touched the tree, and when I told him I had, his face turned pale. “You should have been killed,” he said. It was my boots that saved my life.Within two hours, the workers removed the tree. Soon the snowstorm calmed downbut not my mother.
