How to make a stranger a friend - Just care

The kindness of a stranger - 'You can do it.'
***
I was walking home after a meeting at 10 pm. For such a long time that I didn't give myself the chance to have a long walk in the late evening. The surrounding was just great. People were laughing, drinking, yelling, whispering. Everything was just lively. I walked by a man in the age of 50 carrying a big bag of food. 
I smiled 'It's time for dinner!'
'Oh yes, half of it is for today dinner as I have rice readily waiting for me at home,' he replied with a big grin.
We started continuing the conversation about rice then Vietnamese food. 
After 3 minutes of conversation, he had to turn on the other road to go home. He didn't forget to ask my name and said 'I believe you can successfully do whatever you plan. All the best.'
A gratitude feeling dropped over my whole body, my heart. A stranger cares.

If a stranger can encourage in a stranger without knowing anything about him or her, we all can do it, to our friends, family, people around us. 
Let's do it, today, every day.
