It's better to point out in a loving manner where the youth slipped up while offering practical ways of rectify the situation if possible. Anyone who has ever tried to talk to someone who was just waiting for you to shut up so he could get in his two cents, knows that there are different levels of listening. Listening in order to understand is different from listening in order to be heard. Those adults who are successful with young people listen in order to understand. When an adult expects the best of out of a youth, the youth generally strives to live up to that expectation.
Good leaders know how to spark the imagination and drive in the young people they work with.
The young tend to be idealistic. Most want to do the right thing, but often don't know how to go about it. When shown how they can make a better world, the majority respond. Young people don't need another friend, or another parent. They do need leaders who they can look up to, and go to for help and encouragement.
