There is no saying how much it can brighten a person's day. It costs nothing and requires only a moment of your time. A moment not measurable in time really. It can change someone's mood, their thoughts, their heart. It can light up a room, plant hope and send love. It can encourage a child, and help them to see the humanity we as adults easily loose sight of. It is the shortest distance between two people. It can calm a storm and settle the unsettling. There's nothing quite so beautiful as a smile.
