It is amazing what courtesy will accomplish. It is tragic what a lack of courtesy can bring. We see it every day as we move in the traffic of the cities in which we live. A moment spent in letting someone else get into the line does good for the one who is helped, and it also does good for the one who helps. Something happens inside of us when we are courteous and deferential toward others. It is all part of a refining process which, if persisted in, will change our very natures.”
