[Q]: Article: We can make mistakes at any age.Some mistakes we make are about money.But most mistakes are about people.One might say, "Did Jerry really care when I broke up with Helen?" "When I got that great job, did Jim really feel good about it, as a friend? Or did he envy my luck?" When we look back, doubts like these can make us feel bad. Why do we go wrong about our friends? Sometimes what people want to say hides their real meaning.And if we don't really listen, we miss the feeling behind the words.Suppose someone tells you, "You're a lucky dog." Is he really on your side? If he says, "You are a lucky guy", that's being friendly.But if he says "a lucky dog", there's a bit of envy in those words.Maybe he doesn't see it himself.But he puts you down a little if he brings in the "dog".What he may be saying is that he doesn't think you deserve your luck. "Just think of all the things you have to be thankful for" is another noise that says one thing and means another.It could mean that the speaker is trying to get you to see your problem as part of your life as a whole.But is he trying to? Wrapped up in this phrase is the thought that your problem isn't important.It's telling you to think of all the starving people in the world when you haven't got a date for Saturday night. How can you tell the real meaning behind someone's words? One way is to take a good look at the person talking.Do his words fit the way he looks? Does what he says agree with the tone of voice, his posture, or the look in his eyes? Stop and think.The minute you spend thinking about the real meaning of what people say to you may save another mistake. Therefore, when you hear someone saying, please try to know what he really means.Don't just listen to what he says with your ears but feel the words he uses with your head.In this way you may make fewer mistakes.
Answer: why you keep people friendly without trusting them

[Q]: Article: If you have a watch, don't go to a watchmaker's unless something is wrong with the machinery. Once I had a beautiful watch. And it had kept perfect time. But one night it happened that I forgot to _ it _ . Next morning I went to a watchmaker as I wanted my perfect watch to be set by the exact time. He examined it and said, "The regulator must be pushed up as your watch is four minutes slow. I tried to stop him from doing so, but he didn't listen and pushed the regulator. My beautiful watch began to gain. It gained faster and faster day by day. By the end of the second month it had left all the clocks and watches of the town far behind. I could do nothing but take it to another watchmaker to be regulated. I expected him to regulate the watch at once, but he asked me to come in a week's time. When at last I got my watch back from him, it began to slow down. And I failed to be in time for trains, business affairs, and even missed my dinners. Now I went to a third watchmaker. When I was waiting for him to repair my poor watch, he took it to pieces and said that he would try to finish this work in three or four days. What I could do was to nod my head. After that, my watch went for half a day, and then stopped. So I kept taking my watch from one watchmaker to another. But each watchmaker disappointed me. My watch had cost me two hundred dollars, but I paid for repairs more than two hundred. At last I decided to buy another watch, which I did.
Answer: you'd better not have your watch repaired if nothing has gone wrong with it

[Q]: Article: I sometimes wonder if old Finchley has the right personality to be a research scientist. He keeps asking when he'll be coming back. After all, it was his own fault. Nobody tries out what has just been invented on themselves any more but Finchley. Well, he must have pumped about a thousand cc into himself before I noticed he was clearly becoming smaller. It was funny watching him, because his clothes remained the same in size. They simply piled up around him so that he looked like a small boy in his father's clothes. But he kept getting smaller and smaller. As my colleague Dawson and I watched him, he disappeared! All we could see was Finchley's clothes on the floor. They looked so strange, because the lab coat was on top, shirt and trousers inside and, I suppose, underclothes inside again. It gave me a strange feeling, and I think Dawson was a bit shaken, too. Dawson was sitting on his chair in front of a microscope he'd been using to examine a family of mites . He looked through the scope kind of absently again, and was nearly scared to lose awareness when he found old Finchley waving back from the other end. It seems as if Finchley had taken a free ride on a dust mite and landed on the land of the mite family. Of course, we didn't know till Finchley told us later. But anyhow, as I said, Dawson nearly passed out. He jumped off his chair and pointed at the microscope, too shocked to speak.
