I am pronounced as one letter but written as three,
There are two of me, I am single, I am double,
I can be blue, brown, black or green.
I can be read from right to left or left to right and am still the same.

What am I?

Every dawn begins with me
At dusk I’ll be the first you see
And daybreak couldn’t come without
What midday centers all about
Daises grow from me, I’m told
And when I come, I end all cold
But in the sun I won’t be found
Yet still, each day I’ll be around

A black dog is sleeping in the middle of a black road that has no streetlights and there is no moon. A car coming down the road with its lights off steers around the dog. How did the driver know the dog was there?

What turns everything around but doesn’t move?

It cannot be seen, it cannot be felt,
Cannot be heard, cannot be smelt,
Lies behind stars and under hills,
And empty holes it fills.
Comes first follows after,
Ends life kills laughter.
