Answer:
Responsibility is an important part of being an adult. We should meet our obligations by being reliable, accountable, and dependable. We should follow through on our promises. It is important to be one time for appointments that we have agreed to. Be someone your friends can count on. By creating a habit of reliability, people around us will see us as responsible individuals.
The highlighted sentence, "I am often late for my appointments." is irrelevant to the paragraph's main idea. It does not support or provide any additional information on the importance of being responsible and reliable. Therefore, it can be crossed out.
