This Thai commercial by a security camera company is so shocking and so thought provoking that it's seen by millions of people online.

The story takes place in a shopping street in Thailand. When a bookstore owner opens the shutter to his store, there lies, as always, a homeless man. The owner seems to consider the homeless as a pest, and throws a bucket full of water to the homeless. This was just the ordinary day at this street.

One morning, the owner smelt of urine - it was obvious who the culprit was - so he kicks the homeless. Although the owner's daughter questions the action taken, the shop owner stays disgruntled.

But one day, the homeless stops appearing in front of the shop. When the everyday encounter disappears, even the shop owner is somewhat confused. Seeing that, a lady from the shop next door tells him "he's long gone".

So the shop owner decides to look at the security camera footage... which leads him to tears. The reason? Check out the commercial in its entirety:

It turns out that the homeless was like a guardian of the store. The commercial ends with a line "there's much more truth that you are blind to" - indeed.
