What if your 11 old year was getting ready to move cross country and was in the process of saying goodbye to every friend they have and leaving everything that is familiar to them? Would it be an "exercise of civil disobedience" or just ignoring an arbitrary, never enforced rule to comfort your child?
Have you ever moved your child cross country? Have you held your child while they cried after saying goodbye to their friends for the last time?
Is there absolutely no other way to keep in touch with long distance friends? Exchange phone numbers? Email addresses and/or physical addresses? What did 11 year-olds do before FB?
