You are absolutely right, every human being should be kind to another human being, because when we meet that human being again, he will respect us in the same way.

Someone once said, maybe we meet some good bad people in life so when we meet the good ones, we can appreciate them better. It's wonderful to show kindness. We should have that heart of kindness. It makes the world better.

It is a fact that in life we meet all good and bad people, so what we learn from good people, we should teach other people so that we all can live a good life together and help other people. To help those who need our help at this time.
