A child's laughter brings pure joy to the soul. Children are easily entertained, and find the simplest things funny.
Today, sit down with your kids (if you don't have any, then borrow some), and just talk to them. Ask them what's going on in their lives. Listen to them tell you what makes them happy. Spend an hour, or two, or four with your children. Play a game, watch a movie, play beauty shop, play super heroes, build a fort, play pretend.
Today, be a kid with your kids. Let loose, and enjoy these precious fleeting moments you have with your children.
