When you have an appointment or tell someone you will meet them at a certain time, be prompt. Open the discussion on respect with questions rather than answers. The library is also a place with valuable books used for entertainment and research. The questions might seem simply but if children are taught the proper way to act, they won't know what is right. Respect starts in the home and goes both ways, from parent to child and child to parent.
Respect also goes both ways in school.
As a former teacher I respected my students. I listened to their concerns and found ways to help them whether it was a social problem or an education problem. I did not take their fears as silly and childish. To the children their fears are very real. Go through other examples of how to show respect.
