Article: Driving In America Keep Right The traffic follows the "keep right rule". While driving, drive on the right side of the road. On one-way, multiple lanes  road, the right-most lane would be slowest and left-most lane is fastest. Hand Signals Though indicators  are used for the purpose of showing which direction you are going, knowing some hand signals is very important and are usually always asked in a driving test. When you want to turn right, you can put your left hand out of the window and point upward. When you want to make a left turn, you can reach your left arm out of the window and point to the left. If you want to slow down or stop, you can just point downward. School Buses Yellow school buses have flashing red lights and stop signs that reach out from the driver's side. The drivers use these warning signals when letting pupils on and off. No matter which side of the road you are traveling on, if you come upon a school bus with its lights flashing and a stop sign used, you must stop. It's the law. Remain stopped until the lights stop flashing or the stop sign is removed. Using the Horn Using horns is not common in America. Actually they are very rarely used. You may use your horn to warn walkers or other drivers of possible trouble or to avoid accidents. Do not use your horn to express anger or complain about other drivers' mistakes or to try to get a slow driver to move faster. 
 Answer: Place left hand out of the window pointing backward.

At last, in desperation   the man walked into a police station."Excuse me, officer." he said. "I need some advice. I met this penguin in the street and I don't know what to do with it." A bored policeman looked up from what he was writing and said, "Just take it to the zoo, sir.'' "Oh,all right.''said the man. The next day the man was walking along the street, still accompanied   by the penguin, when he met the policeman he'd spoken to the day before.The policeman was not pleased to see them."I thought I advised you to take that animal to the zoo, " he said. "Well, yes, officer, you did.And I did take him to the zoo, " the man explained. "And we had a great time. But we can't go to the zoo every day.I thought today I'd take him to the movies.''

Article: It was a winter morning, just a couple of weeks before Christmas 2005.While most people were warming up their cars, Trevor, my husband, had to get up early to ride his bike four kilometers away from home to work.On arrival, he parked his bike outside the back door as he usually does.After putting in 10 hours of labor, he returned to find his bike gone. The bike, a black Kona 18 speed, was our only transport.Trevor used it to get to work, putting in 60-hour weeks to support his young family.And the bike was also used to get groceries , saving us from having to walk long distances from where we live. I was so sad that someone would steal our bike that I wrote to the newspaper and told them our story.Shortly after that, several people in our area offered to help.One wonderful stranger even bought a bike, then called my husband to pick it up.Once again my husband had a way to get to and from his job.It really is an honor that a complete stranger would go out of their way for someone they have never met before. People say that a smile can be passed from one person to another, but acts of kindness from strangers are even more so.This experience has had a spreading effect in our lives because it strengthened our faith in humanity as a whole.And it has influenced us to be more mindful of ways we, too, can share with others.No matter how big or how small, an act of kindness shows that someone cares.And the results can be everlasting. 
 Answer: They used it for work and daily life.

Why was the bike so important to the couple?
