Being responsible means being accountable for what you do - for your actions, words, and behavior. It also means doing the right thing at the right time, so others can trust and depend on you. A responsible person is trustworthy and dependable. People can count on you to do what is right; and, when you make a mistake, you will admit it, apologize for it, and correct the actions that led to the mistake. When you demonstrate responsible behaviors to others, you inspire others to want to be better people too. It is a key ingredient in the recipe of success and a major factor in being a person with integrity.  

But It's Not My Fault, written by Julia Cook, is abook about "Noodle" and how "things happen to me that get me into trouble". It is a book that demonstrates to children what it means to take RESPONSIBILITY for their actions.

      A responsibility might be a task you are expected to do. For example, your parents expect you to brush your teeth. Brushing your teeth is “a responsibility” and it is your responsibility to brush your teeth every day. Another task example is that your teacher expects you to finish your homework on time and to do your best job. So it’s your responsibility to do your homework.
