Brighteyes just left for a sleepover with her aunt. Before she left we reviewed the rules of her behavior: no hitting, no kicking, no screaming, no shouting, only one movie, don't wander from your table in restaurants, and so on.
"That's so many rules. I have trouble remembering them."
"Yes but most of the rules can be summed up in one rule: don't do things to other people that you don't want them to do to you. You don't like people hitting you? Then don't hit other people. You don't like people screaming at you? Then don't scream at other people."
"Oh! That's easy to remember! And it does cover most of the rules."
"That's right. You can also talk it over with your aunt if you have any questions about it."
As long as she doesn't get too tired and forget, I don' t think we have anything to worry about.
