"There's nothing more satisfying than seeing a happy and smiling child. I always help in any way I can, even if it's just signing an autograph. A child's smile is worth more than all the money in the world."

 -Lionel Messi.

It’s great when kids are happy. They’re easy to upset, and when they’re not you know that you’re doing something right. They’re too young to play the strategy card or fake emotions. It’s good, honest happiness, and no-one has to worry about them which is less stress for everyone. If they do get upset, everyone wants to help them out, even if it’s just for a bit of piece and quiet. However, I doubt that a scrap of paper with someone’s signature on it is going to help them much. They’d probably appreciate it more on a cheque so that they can purchase what they want, although they’d struggle to understand what this gesture would mean and there’d still be a considerable wait for their wanted attentions to arrive. But it’s about trying to find them happiness there and then, or at least until it’s time to depart from them and it becomes someone else’s problem.
