I welcome the day with a show of light, I stealthily came here in the night. I bathe the earthy stuff at dawn, But by noon, alas! I'm gone.

Inside the white house, there is a red house.
Inside the red house, there are lots of babies.

What is It?

There's a day, that comes around once a year.
To celebrate the man, you hold dear.

and slower when I am thick
The wind is my energy
