They say communication among family is a two way street. One person talks one way and the other person talks back. I understand that. But a lot of things can happen on a two way street. Small things may be getting stuck in traffic and having to wait or veering off course and colliding with someone on the other side. But there are other dangers like rear-ending someone because you didn't pay attention to the red light. You're car can break down and some big hairy guy comes to give you a "lift". Tell me is that really something you want happening in your family?
