Answer:
I tremble at each breath of air and yet can heaviest burdens bear.
The more it dries, the wetter it becomes. What is it?
I go from house to house a messenger small and tight. Whether it rains or snows I sleep outside at night.
I am the kind of ant that's good at math.
I run around the city but I never move.
Runs over fields and woods all day. Under the bed at night sits not alone, With long tongue hanging out, Resting at your feet until we go for a walk
