You looked on the fellow as low, coarse, cheap, unfit to associate with respectable persons.

The next time you use a word that you should be ashamed to have your mother or sister hear just think that you are following the example of that loafer.

You are lowering yourself in the eyes of somebody, even though you may not think so at the time.

Perhaps one of your companions may be a person who uses such language freely, and yet he has never before heard it from you.

He laughs, he calls you a jolly good fellow to your face; but he thinks to himself that you are no better than anybody else, and behind your back he tells somebody what he thinks.
