I had an experience recently with someone admitting to me that he had made a mistake fifteen years ago. He told me he had been the manager of a grocery store in the neighborhood where I grew up, and he asked me if I remembered the egg cartons. Then he related an incident and I began to remember vaguely the incident he was de scribing. I was about eight years old at the time, and I had gone into the store with my mother to do the weekly grocery shopping. On that particular clay, I must have found my way to the dairy food department where the incident tool place. (80) There must have been a special sale on eggs that day be cause there was an impressive display of eggs in dozen and half-dozen cartons. The cartons were stacked three or four feet high. I must have stopped in front of a display to admire the stacks. Just then a woman came by pushing her grocery cart and knocked off the stacks of cartons. For some reason, I decided it was up to me to put the display back together; so I went to work. The manager heard the noise and came rushing over to see what had happened. When he appeared, I was on my knees inspecting some of the cartons to see if any of the eggs were broken, but to him it looked as though I was culprit(罪犯). He severely scolded me and wanted me to pay for any broken eggs. I protested my innocence and tried to explain, but it did no good. Even though I quickly forgot all about the incident, apparently the manager did not. How old was the author when he wrote this article？ A．About 8. B．About 18. C．About 23. D．About 15.

I was standing on the corner of the street with a cigar that I wanted to light. I had no match. I waited till a decent, ordinary man came along. Then I said: "Excuse me, sir, but could you oblige me with the loan of a match？" "A match？" he said, "why, certainly." Then he unbuttoned his overcoat and put his hand in the pocket of his waistcoat. "I know I have one," he went on, "and I'd almost swear it's in the bottom pocket — or, hold on, though, I guess it may be in the top — just wait till I put these parcels down on the sidewalk." "Oh, don't trouble," I said. "It's really of no consequence." "Oh, it's no trouble, I'll have it in a minute; I know there must be one in here somewhere"—he was digging his fingers into his pockets as he spoke — "but you see this isn't the waistcoat that I generally…" I saw that the man was getting excited about it. "Well, never mind," I protested; "if that isn't the waistcoat that you generally — why, it doesn't matter." "Hold on, now, hold on!" the man said. "I've got one of the cursed things in here somewhere. I guess it must be in with my watch. No, it's not there either. Wait till I try my coat. If that damned tailor only knew enough to make a pocket so that a man could get at it!" He was getting pretty well worked up now. He had thrown down his walking-stick and was searching his pockets with his teeth set. "It's that cursed young boy of mine," he exasperated; "this comes of his fooling in my pockets. By God! perhaps I won't warm him up when I get home. Say, I'll bet that it's in my hippocket. You just hold up the tail of my overcoat a second till I…" "No, no," I protested again,"please don't take all this trouble, it really doesn't matter. I'm sure you needn't take off your overcoat, and oh, pray don't throw away your letters and things in the snow like that, and tear out your pockets by the roots! Please, please don't trample over your overcoat and put your feet through the parcels. I do hate to hear you swearing at your little boy, with that peculiar grumble in your voice. Don't — please don't tear your clothes so savagely." Suddenly the man gave a grunt of joy, and drew his hand up from inside the lining of his coat. "I've got it," he cried. "Here you are!" Then he brought it out under the light. It was a toothpick. Yielding to the impulse of the moment I pushed him under the wheels of a trolley-car and ran.
