Input: Consider Input: Article: Any mistake made in the printing of a stamp raises its value to stamp collectors.A mistake on a two-penny stamp has made it worth a million and a half times its face value. Do you think it impossible? Well,it is true.And this is how it happened. The mistake was made more than a hundred years ago in the former British colony of Mauritius,a small island in the Indian Ocean. In l847 all order for stamps was sent to London Mauritius was about to become the fourth country in the world to put out stamps. Before the order was filled and the stamps arrived from England,a big dance was planned by the commander-in-chief of all the armed forces on the island.The dance would be held in his house and letters of invitation would be sent to all the important people in Mauritius.Stamps were badly needed to post the letters.Therefore,an islander,who was a good printer,was told to copy the pattern of the stamps.He carelessly put the words "Post Office" instead of "Post Paid", two words seen on stamps at that time,on the several hundred that he printed. Today, there are only twenty-six of these misprinted stamps left-fourteen One-penny Reds and twelve Two-penny Blues, Because there are so few Two-penny Blues and because of their age, collectors have paid as much as$16,800 for one of them.

Input: Consider Input: Article: Not being the greatest fan in the world of live performance, I took a deep breath before I en tered the building, the castle theatre, and prepared myself to be bored, expecting to find it more interesting to watch the audience than the show. Then I got the shock of my life. Wadaiko Inchiro are a group of ten young Japanese men and women using traditional drums with a history going back more than 1500 years. The drums were once used for festivals and religious ceremonies and also as a means of communication during wars. Today they give an ear-blasting performance which punches out rhythms with the power to wind you. They're a welcome relief from the Scottish pipers. Unlike other performances, the best seats are at the back of the house. Not only will your ears be protected from full blast, but you will get a fantastic view of the whole set. On stage are some of the biggest drums you will ever see and a cast wearing red, white and black headscarf. There had been almost no publicity for the show, but the house was full of people desperate, one could only assume, for something a bit different from the unrelenting performances appearing at this world-famous festival. The solid 60-minutes show starts as it means to go on. The drums rumble into fever-pitch action as the ten-strong company strike their sticks with startling control. Their rhythmic frenzy almost immediately drugs you into submission. Trapped inside the beating of the drums, you carried swiftly through warrior war cries to emotional rhapsodies . Not only is this display musically impressive, but the dance is strikingly beautiful. Moving between the enormity of the drums, the slight Japanese characters have complete synchronicity with the flying of their sticks, which they ceremonially cross and use to command. The biggest drum is played only by Inchiro, the leader of the group. When I ask why this is so, he refuses to admit that he is being precious about this monster of an instrument and says, "When someone else can play it as I do, I will happily move aside." Dressed all in red, he stands before it as thought he is worshipping at an altar; as he raises his sticks to the drum, he touches it sometimes tenderly and sometimes murderously. Inchiro and his drum produce a range of sounds from thunder to the trickle of rain.

Input: Consider Input: Article: All things change except barbers, the ways of barbers, and the surroundings of barbers. These never change. What one experiences in a barber's shop the first time he enters one is what he always experiences in barbers' shops afterward till the end of his days. I got shaved this morning as usual. A man approached the door from Jones Street as I approached it from Main--a thing that always happens. I hurried up, but it was of no use; he entered the door one little step ahead of me, and I followed in and saw him take the only empty chair, the one headed by the best barber. It always happens so. I sat down, hoping that I might sit in the chair belonging to the better of the remaining two barbers, for he was a bit ahead. I watched the probabilities with strong interest. When I saw that No. 2 was gaining on No. 1, my interest grew to solicitude . When No. 1 was gradually losing the race, my solicitude rose to anxiety. When No. 1 caught up again, and both were about to finish and say "Next!" first, my very breath stood still with the _ . But when I saw that he had lost the race by a single instant, I rose angrily and quitted the shop, to keep from falling into the hands of No. 2; for I have none of that firmness that enables a man to look calmly into the eyes of a waiting barber and tell him he will wait for his fellow-barber's chair. I stayed out fifteen minutes, and then went back, hoping for better luck. Unfortunately, all the chairs were occupied now, and four men sat waiting, silent, and looking bored, as men always do who are waiting their turn in a barber's shop. I sat down and waited. At last my turn came. A voice said "Next!" and I give in to No. 2, of course. It always happens so. I smiled and said that I was in a hurry, and it affected him as strongly as if he had never heard it. He explored my hair with his claws and suggested that it needed trimming . I said I did not want it trimmed. He explored again and said it was pretty long for the present style. I said I had had it cut only a week before. He stopped for a moment, and then asked "who cut it?" I stared at him from the mirror and replied "You did!". Then a dog-fight attracted his attention, and he ran to the window and stayed and watched it...
Answer: he was angry at the slow speed of "No. 1"
