"Four Years Back"

Four years ago I was fourteen years old. Back then I wasn't able to do a lot of things. For instance, I wasn't able to clean the entire house by myself. Now I am able to clean the entire house without any help in about an hour or an hour and a half. I learned how to somewhat drive a car. I learned this weird way of flaring one of my nostrils up at a time. While at school, I was able to memorize the whole periodic table. In the past four years, I learned more about life and how to survive while out in the world.
