For this, there are many reasons but most of them stem from not being able to properly understand their teens. It is a dangerous gap because parents will have to communicate with their teens about a wide variety of issues during the most important years of their lives. Thus, parents must know how to communicate openly and honestly with their teens. Here are a few tips to make communication easier between parents and teenagers. 1. Try not to talk down to your teens. Make them feel as if their views really matter, which not only helps your discussions with your teen but bring you closer to him. 2. Imagine what it would be like to be a teen. Try to remember some of the negative feelings you experienced as a teenager and apply it to your teen's situation. 3. Never make negative remarks to your teen about what she has said or done. 4. Remember how much courage it would have taken for your teen to come and talk to you about his personal issues. So listen respectfully. 5. Don't ignore your teen's feelings because it is usually a cry for help. For instance, if your teen is unusually angry, it may be time to spend a bit of quality time with your teen to determine what is wrong and where he is coming from. It is, therefore, necessary for parents to strive to keep lines of communication open at all times with their teens. Try to remember what it was like to be a teenager and how vulnerable you felt. Then you will be well on your way to help your teen communicate more openly and honestly.

Example Input: Article: For generations here in the deepest South, there had been a great taboo : publicly crossing the color line for love. Less than 45 years ago, marriage between blacks and whites was illegal, and it has been forbidden for much of the time since. So when a great job about an hour's drive north of the Gulf Coast attracted him, Jeffrey Norwood, a black college basketball coach, had reservations. He was in a _ relationship with a woman who was white and Asian. "You're thinking about a life in South Mississippi?" his father said in a skeptical voice, recalling days when a black man could face mortal danger just being seen with a woman of another race, regardless of intentions. "Are you sure?" But on visits to Hattiesburg, the younger Mr. Norwood said he liked what he saw: growing diversity. So he moved, married, and, with his wife, had a baby girl, who was counted on the last census as black, white and Asian. Taylor Rae Norwood, three, is one of thousands of mixed-race children who have made this state home to one of the nation's most rapidly expanding multiracial populations, up 70 percent between 2000 and 2010, according to new data from the Census Bureau. In the first comprehensive accounting of multiracial Americans since statistics were first collected about them in 2000, reporting from the 2010 census, made public in recent days, shows that the nation's mixed-race population is growing far more quickly than many researchers had estimated, particularly in the South and parts of the Midwest. That conclusion is based on the bureau's analysis of 42 states; the data from the remaining eight states will be released soon. In North Carolina, the mixed-race population doubled. In Georgia, it grew by more than 80 percent, and by nearly as much in Kentucky and Tennessee. In Indiana, Iowa and South Dakota, the multiracial population increased by about 70percent. Census officials estimated the national multiracial growth rate was about 35 percent since2000 according to the known result, when seven million people ----- 2.4 percent of the population chose more than one race.
