"The first patient is a thing which one remembers all one's life. Mine was commonplace, and the details are of no interest. I had a curious visitor, however, during the first few months after my plate went up. It was an elderly woman, richly dressed, with a wickerwork picnic basket in her hand. This she opened with the tears streaming down her face, and out there waddled the fattest, ugliest, and mangiest little pug dog that I have ever seen. 'I wish you to put him painlessly out of the world, doctor,' she cried. 'Quick, quick, or my resolution may give way.' She flung herself down, with hysterical sobs, upon the sofa. The less experienced a doctor is, the higher are his notions of professional dignity, as I need not remind you, my young friend, so I was about to refuse the commission with indignation, when I bethought me that, quite apart from medicine, we were gentleman and lady, and that she had asked me to do something for her which was evidently of the greatest possible importance in her eyes. I led off the poor little doggie, therefore, and with the help of a saucerful of milk and a few drops of prussic acid his exit was as speedy and painless as could be desired. 'Is it over?' she cried as I entered. It was really tragic to see how all the love which should have gone to husband and children had, in default of them, been centred upon this uncouth little animal. She left, quite broken down, in her carriage, and it was only after her departure that I saw an envelope sealed with a large red seal, and lying upon the blotting pad of my desk. Outside, in pencil, was written: 'I have no doubt that you would willingly have done this without a fee, but I insist upon your acceptance of the enclosed.' I opened it with some vague notions of an eccentric millionaire and a fifty-pound note, but all I found was a postal order for four and sixpence. The whole incident struck me as so whimsical that I laughed until I was tired. You'll find there's so much tragedy in a doctor's life, my boy, that he would not be able to stand it if it were not for the strain of comedy which comes every now and then to leaven it. "And a doctor has very much to be thankful for also. Don't you ever forget it. It is such a pleasure to do a little good that a man should pay for the privilege instead of being paid for it. Still, of course, he has his home to keep up and his wife and children to support. But his patients are his friends--or they should be so. He goes from house to house, and his step and his voice are loved and welcomed in each. What could a man ask for more than that? And besides, he is forced to be a good man. It is impossible for him to be anything else. How can a man spend his whole life in seeing suffering bravely borne and yet remain a hard or a vicious man? It is a noble, generous, kindly profession, and you youngsters have got to see that it remains so."
