Answer:
I am the best thing that can happen after a stick hits a ball.
I am all around you but you cannot see me. I have no throat but you can hear me. Valued during summer but despised in the winter.
What can you hold in your right hand but not in your left hand?
The more you work the more I'll eat.You keep me full I'll keep you neat.
I build up castles. I tear down mountains. I make some men blind, but I help others to see. What am I?
Who makes it, has no need of it. Who buys it, has no use for it. Who uses it, can't see it. What is it?
