I came  back own  home from my  mother's house over 8pm. My  husband  and  son were  eating dinner,  cause they were busy with their works. I was looking  at  them eating while  talking the further of our family and something what son's girlfriend. That moment I gradually felt happiness around myself, very intense. I haven't had that beautiful sense for a long time. I am thinking, actually, happiness  is very  simple and common.  Every one all  has. When we are envying or looking up at  others' happiness, look back, but find that  we are being looked up at and envied  by others.
