It's not only that they come back home, it's that you need to sit back sometimes, and others you need to be there to listen or coach or whatever they need. Its up to the parent most of the time to make the judgement call on which is wanted or needed. Even when and if they ever have children I feel like there will always be something. It's really very beautiful but it's also so very hard sometimes especially when your own judgements are completely different from theirs. That being said, I wouldn't have it any other way.
