But what of the Jake, in this case--the prime factor of the problem? The Jake in this case, of course, is no other than our only son, George. No trouble of any sort was experienced by him in the various stages of his journey. Upon his arrival, there were a number of new people to meet and various elements of interest in the new surroundings to occupy his attention. For the time being, he forgot to think of the mother he had left behind. Hours later, as they are starting a game of tennis, it suddenly occurs to him that he has not yet sent his telegram home, but as it would be a bother to go back to the house now and he feels like going ahead with the tennis game, he makes a mental note and puts it off. It is not until dinner time that he thinks of it again and when he finds that the telephone is out of order and he would have to motor in to the telegraph office, its doesn't seem worth the trouble. He has allowed so much time to go by already that he decides the most satisfactory way out of it is to wait until he finds time to write a letter and explain, as an excuse for not keeping his promise, that the telephone wasn't working. Before he has an opportunity to write his letter, the telegram arrives from home disclosing his mother's anxiety--whereupon he feels ashamed and sorry, and hurries to the telegraph office to send a reply. This is a more or less typical example of a great many cases where lack of consideration for others is not necessarily due to a lack of affection or sympathy, but comes from a lack of thoughtfulness and understanding. George may love his mother very much and he would not voluntarily hurt her feelings, or be the cause of her suffering. The sight of his mother in tears would cause him unhappiness and he would gladly make a real sacrifice in order to comfort her. But the sight of his mother's suffering, or the thought of his mother's suffering, is not before him--it does not enter into his calculations or motives of conduct. In order for this to take place, a certain amount of reflection and imagination is required on his part. In the case of Harry and Jake and the apple, we assumed that some one came along and called Jake's attention to the unhappiness of Harry. When Jake was made to see and realize, he responded with a feeling of consideration. But in the case of George and the vast majority of cases where this question is involved, no one comes along to explain to you. If the pleasure or pain of others is involved in what you do, the thought of that must come from yourself. Very often those others are not present at the time and the consequences may not be immediately and superficially apparent. Imagination, reflection, and a habit of mind, may be needed to realize the effect upon them.
