What got to me, though, was how the VS boys did not clear their trays when they got up to leave. Some placed their empty drink cups and wrappers on the trays, but no one bothered to empty the filled trays.
The trash bin was next to the tables they were occupying — at most three steps away. The appalling thing was seeing how the teacher did not bother to ask the boys to clear their trays — she just stood there talking to the boys.
Then they all left. The area they had occupied looked as if a tornado had swept through it.
