The great advantage to being a dad is the excuse to spend Saturdays playing. I realized once that I would have only 936 weekends with each child before they left me for adulthood and I don't want to waste a single one. So Saturdays have been christened Family Fun Day in which we try to spend a significant amount of time enjoying life and each other. There will be plenty of time for working weekends when they're grown. Then I'll drive by empty playgrounds and remember when.
