Thanks for coming and saying goodbye

When Happiness knocks at my door,

That means He is about to leave.

When Sadness asks me to meet,

That means She wants to say goodbye.

"Oh Sadness and Happiness of mine!

You are all my friends, my guests.

When you come, 'welcome to my nest!'

When you leave, hug and say 'good night!'

I am just a child, living in the sky

Playing all day, dreaming all night,

Knowing nothing about this short life.

Thanks for coming and saying goodbye."
