We live in the countryside. Most of which we see is beauty and nature. One of the exceptions to the beauty is the litter some people throw out their windows as they are driving on the roads. One of the few drawbacks to living in the countryside is that public service, such as litter collection, are little available than they are closer to the city.
A helping habit that my family practise regularly are picking up litter in our surrounding area. We have become so accustomed to do this that my little brother will often say, “There's some litter, Daddy, stop the car!” And we would often pull over and pick it up. It may seem strange, and we actually enjoy it. We pick up litter in parks, on sidewalks, practically anywhere. Once I even saw a complete stranger picking up litter close to where we live in. He smiled at me and said, “I saw you doing it, and it seemed like the good idea.”
