Article: I was an introvert by nature. For as long as I remember, showing a sincere smile when meeting someone had never been easy. When meeting people, instead of being excited, I often felt upset or self-disturbed. But we all know having friends is important. The more friends you have, the more opportunities you get, no matter whether it's a job opportunity, a romantic relationship, or a business partner. So a smile is important to making others feel comfortable. Mother Teresa said, "Every time you smile at someone, it is an action of love, a gift to that person and a beautiful thing." The smile I'm talking about is not to make a face to someone. I'm talking about those wide smiles you make when meeting old friends. So I've discovered a trick. I call this technique "Oh, it's Jamie!" When I meet someone, I imagine him as an old friend of mine called Jamie. He was my first friend when we were still kids. It's no secret why my smile is as wide as I can possibly make. And the best part, whenever you're friendly to others, they are friendly in return. You're not hearing this from me. A research which was done early by scientists actually backs this claim. So do remember to give it a try.

Article: In a survey of 1,500 European hotel managers, Americans were ranked second, behind the Japanese, as the world's best tourists. In the survey, conducted in April by the online travel site Expedia's German branch, Americans were seen as the most likely to try to speak a foreign language and the most interested in tasting local food. Americans came in third, behind the Japanese and British, as the "most polite" tourists, and third, behind the Japanese and Germans, as "best behaved". And ---- Americans were ranked far and away as the world's most generous tippers and biggest spenders. On the other hand, Americans were seen as the shabbiest dressers, the most likely to complain and the second noisiest. Who is louder? Only the Italians. Some of the other findings: Russians were as the least polite travelers, followed by the Israelis and French. The stingiest tippers: the Germans, followed by the French and Israelis. Italians, by far, were ranked as the best dressers, followed by the French and Spanish. In terms of bad dressing, the British were a distant second to Americans, followed by the Germans. Who's the most unwilling to try speaking in a foreign language? The French, the British and the Italians, in that order. The Chinese are the most reluctant to taste foreign food, followed closely by ---- this is strange ---- the British, whose home _ is probably the world's most seriously laughed at ( a little unfairly, perhaps). And, finally, the overall award for "worst tourist in the world" goes to the French, with the Indians and Chinese.

question:
Article: Steve knew he'd been adopted as a baby, and when he turned 18, in 2003, he decided he'd try to track down his birth mother. The agency from which he'd been adopted gave him his mother's name: Tallady. But online searches didn't turn up any results about it, and Steve had to let it go. In 2007, though, he searched for the name again online. This time, the search results included a home address near the Lowe's store where Steve, then 22, worked as a deliveryman. When he mentioned the coincidence to his boss, his boss said, "You mean Tallady, who works here?" Steve and Tallady, a cashier, had said hello to each other a few times at the store, but they'd never really talked. He hadn't even known her name. Steve thought there was no possible way she was his mother though they shared the same name. For a few months, Steve avoided Tallady. "I wasn't sure how to approach her," he told a local reporter. Finally, the agency volunteered to arrange their reunion. When Tallady realized that the nice guy she'd been waving at was his son, she sobbed. She'd always hoped to meet her birth son one day. Later that day, mother and son talked for almost three hours at a nearby bar. She'd given him up for adoption in 1985, when she was 23. "I wasn't ready to be a mother," she told him. Married with two other children, Tallady says, "I have a complete family now."
