Any random act of kindness is something that will always pay off. But that increases a hundred-fold when you show kindness to a dog. The proverbial man's best friend is truly just that.
In this Thai ad for Kiatnakin Bank shows how a dog shows a man his gratitude in return for a simple act of kindness. The man gives the dog his lunch. The dog makes it his mission to make the man happy. The ad may be a tint bit of an exaggeration, but it is true in its essence.
All a dog wants from you, is a bit of affection and care. In return, it gives you everything it has.
