To make a difference in someone's life you don't have to be brilliant, rich, beautiful or perfect. You just have to care.
Questioning means to have or ask questions. When you look for questioning quotes you will find some from people of all ages, including small children and the elderly. If you have a questioning attitude then you want to know the answers to everything, and you are willing to search them out if necessary. When police are questioning a suspect they are asking the individual questions to determine if the person committed a crime or not. In some eras in the past questioning authorities and current laws was a given, especially laws that seemed unfair like segregation. A questioning attitude is not always a positive though. If a threat is made and you are in danger it is better to get out of there and worry about the reason why something happened later.
