I must say the CHILD acronym is a wonderful one, and a new thing I've learnt. We can't deny the beauty of the character of a child. Then we get to wonder how we lost those qualities as adults. Like you said, I guess life and society happens to people.
Yes, it's good we smile, often. We never know who needs it. That might just be the healing someone needs and we also; that's in case it was a forced smile. Seeing someone smile because of our smile is a good experience. It's about carrying a positive facade. If we can't help the problem at hand, why throw a long face all around? This was inspiring.
Nice pictures by the way.
