Well maybe this story will shock you more, actually I posted it on another blog but nevertheless:
A little boy of about 9 years old ran out to the garden of his shtiebel during leining one Shhabbos to play. When he returned to the Bais Medrash, he noticed that an elderly man had occupied his seat. H e politley claimed his place . A few minuites later, the father of that little boy approached the elderly man and said, ,yes, this indeed is my boy,s seat, please find somewhere else to sit,
So if parents dont enforce basic DE for others, how do you expect the kids to have it?
