Q: Article: What could be cuter than your puppy giving his doggy friend a kiss on the nose? Nothing, really. But is your dog actual-fly planting a kiss on his friend? Yes, but that's only one of the reasons your dog may lick another dog's nose. Here are some other reasons why your dog may lick another dog's nose. During an introduction, a shy and lower-ranking dog will lower his head, avoid direct eye contact and gently extend his tongue to lick the nose of a more confident and high-ranking dog. The first dog licks the nose of the second dog to simply make it know that:he comes in peace. Dogs who are already friends will also trade kisses. Two strongly bonded dog pals will lick and clean each other. They give each other "dog kisses" showing friendship. Puppies also "kiss" their mothers, but it's not a gesture of love. When puppies stop suckling their mothers' tits for milk and start to eat semisolid food instead;they lick their mothers' mouths and noses in the hope of getting the mother to regurgitate some semi-digested food. So how to help your _ dog make friends with other dogs? You can carefully select confident-but-friendly and good-tempered dogs to play with your shy dog, to help him develop his social skills. Also consider taking him to a special training class that focuses on socialization and positive training technique. Do not disturb them when your two dogs play "kiss" briefly with each other. Sit back and enjoy this display of friendship. Then call them over and have them do a command such as "sit'' or "shake paws". Offer them treats as a reward for being good to each other. If you foster a dog and have three or more resident dogs, introduce the foster dog to your brood dog one at a time and let muzzle licking between them happen naturally. Start with your least reactive or most friendly dog. Never force an in production between the dogs because this can deepen the foster dog's submissiveness or spark a fight.

Q: Article: A traveler once visited a city where everyone wore blue. Puzzled, he went to a dyer and said, " Please dye the handkerchief red." "I don't know how to dye red." "Then dye it green." "I can't dye it green. There are forty master dyers in this city, and every one of us can dye only blue." "I can dye all color1s," said the traveler, "Hire me and I'll teach you my art." "We never allow a stranger to enter our craft ", said the dyer. The traveler made the same offer to the other master dyers, but none would hire him. So he began his own dye shop. Folks soon crowded around asking, "What are all these beautiful color1s called?" He answered, "This is red and that is yellow," and so on. Everyone began bringing him cloth to dye.

Q: Article: It could happen just about any time you step out in public. You get onto an almost-empty bus, but the next passenger in decides to ignore dozens of empty seats to sit right next to you. While you're waiting in line at a supermarket, the next customer insists on standing only two inches behind you and shouting into his cell-phone. You go into a public restroom, and the next person to enter decides to use the next stall. Transgressions like these don't just make us feel uncomfortable; we often feel anxious, alarmed; and violated . It is the attack of the personal-space invaders. In any society, shared definitions of personal space govern how we interact with other people. People living in densely populated cities like Mumbai, Beijing, or Mexico City tend to require less personal space than people living in sparsely populated places within the country. In America, New Yorkers often have smaller requirements than residents of western states, like Montana, Shenandoah and Wyoming. Because everyone has different standards, gestures that are innocent in one place can be interpreted as opposite in another, especially in Britain. As the British etiquette website Debrett puts it, as a British person, somebody standing too close may make you "focus less on what somebody is saying than on how close they are to you". Simple acts like putting an arm around someone you don't know may seem friendly in China, but they can make us very uncomfortable. People from many European countries such as France and Spain kiss each other on the cheek when they meet, yet to British person, this seems too friendly and "touch-freely". The website explains! "The British are not backslappers and generally do not show affection in public". Are British people unfriendly? Far from it. The website adds that they are not as " _ ' as they may seem, but very friendly and helpful to foreigners. However, remember not to be too close. If you are going to come closer than an arm's length, please let them know.
Answer: keep an arm's length away from him/her

A:
According to the passage, if you were meeting a British for the first time, it would be polite of you to _ .
