Last night, I saw two homeless men to come in for dinner in a restaurant. They sit there but didn't order nothing. So I decided to order dinner for them and pay for it. Meanwhile, I asked the manager not to telling them about it. They were so surprised that they tried hardly to get my identity of the manager. After several unsuccessful try, they smiled, thanked him and left. Then the manager asked me that I knew them. My answer was no. He said it should be more kindnesses like that in world.
