My kids grew up witha parent working nights (mom) and a parent working days (me). She got them off to school and I was there right after the came home. They knew that the old man would be there and there was no chance for shennanigans. It worked well till they got freedom and then it all went to hell in a handbasket!
You did a great job. They are wonderful kids! I was a bit (ha!) goofy in my twenties, but it all comes back to the basics of how chldren were reared when they were little. I had the basics and that's what counts. Unfortunately, today's kids don't often get a shot at that initial training and have no way to get back.
