Mmm.
People really should listen when others are trying to tell them something. But if they did...well, they wouldn't be *people*, would they? Can't force the horse to drink, after all. It's said that the burnt hand learns fastest...people have to be able to make their own decisions, even when you can see that it's going to take them down a path other than the one they intended to go strolling along. They have to be able to grow and develop at their own pace...otherwise it isn't growth, simply conformity.
