You may suppose that I should not soon have got tired of watching them and listening to the little treble buzz of voices that went on, but I was interrupted. Just in front of me I heard what I can only call a snigger. I looked down, and saw four heads supported by four pairs of elbows leaning on the window-sill and looking up at me. They belonged to four boys who were standing on the twigs of a bush that grew up against the wall, and who seemed to be very much amused. Every now and again one of them nudged another and pointed towards me; and then, for some unexplained reason, they sniggered again. I felt my ears growing warm and red. "Well, young gentlemen," I said, "you seem to be enjoying yourselves." No answer. "I appear to be so fortunate as to afford you some gratification," I went on, in my sarcastic manner. "Perhaps you would do me the honour of stepping into my poor apartment?" Again no answer, but more undisguised amusement. I was thinking out a really withering remark, when one of them said: "Do look at his nose. I wonder if they know how ridiculous they are. I _should_ like to talk to one of them for five minutes." "Well," I said, "that can be managed very easily, and I assure you I should be equally glad of the opportunity. _My_ remarks would deal with the subject of good manners." Another one spoke this time, but did not answer me. "Oh, I don't know," he said, "I expect they're pretty stupid. They look it--at least this one does." "Can they talk?" said the third. "I've never heard 'em." "No, but you can see them moving their jaws and mouths and things. This one did just now." I saw how it was now, and, becoming cooler, I recognized that these youths were behaving very much as I might have done myself in the presence of someone who I was sure could neither see nor hear me. I even smiled. One of them pointed at me at once: "Thought of a joke, I s'pose. Don't keep it all to yourself, old chap." At this moment the fourth, who had not said anything so far, but seemed to have been listening, piped up: "I say! I believe I know what it is that makes that hammering noise: it's something he has got in his clothes." I could not resist this. "Right again," I said; "it's my watch, and you're very welcome to look at it." And I took it out and put it on the window-sill.
