Answer:
This guy crossed a road and everyone wants an explanation.
I have a little pool with two layers of wall around it. One white and soft and the other dark and hard. Amidst a light brown grassy lawn with an outline of a green grass.
When I get closer my tail grows longer but when I go away my tail leads the way.
I am a way to say goodbye to your sweetheart
You write on me and secrets I can keep in places never seen. I spin like a top. Though stiff as a board, I'm often described like a mop. What am I?
Of these things - I have two. One for me - and one for you. And when you ask about the price I simply smile and nod twice.
