Some see their duty and do it. Impressive.
To add to the childhood memories department, my elementary school assigned sixth graders crossing guard duties at the intersections around the school, providing them a vest and yellow flag to direct traffic. Very low cost and taught the kids responsibility.
I remember those too, and the sixth grade hall monitors. The sixth graders who had proved themselves responsible enough to take on and learning even more about responsibility, demonstrating their good citizenship and having good grades, those who got to be crossing guards and hall monitors where looked up to and respected and something to aspire to by the other kids back then. Now days, sadly in many places, they are more likely to get beaten up for being nerds or snitches or whatever.
Our schools had sixth graders who served as crossing guards in my small NJ town. The student safety patrol controlled the younger students, not the traffic. Only the adult crossing guard, who was at the busiest intersection, was allowed to stop traffic.
