Father's Day is a national event or is at least advertised as one. But, the sad fact is, many people have fathers who weren't active parts of their lives. Statistics prove as much, especially in the United States where the special day originated.
It is said that a group of church women took mother's day cards into prison and so many wanted them to send to their mother, they ran out. So, they stocked up for father's day and went back. Only a few wanted them. That tells you that those who don't have active fathers in their lives can easily have problems that land them in trouble, like a prison. That is why father's day isn't celebrated by many - many have fathers they don't feel deserve a card.
