When I was probably 8 I followed Ma to Ipoh to visit Pa.

We had to take the underground street cross, and as we walked we passed by a woman. She smiled, and then I looked up and saw Ma also smiled.

I asked if Ma knows her. Ma says no, but a smile is charity.

Till today I remember what Ma said. Smile is charity. You could live in the best city in the world, have everything, but if you are stingy and such a miser to donate and spread happiness to the world around you, what that makes of you?
