Answer:
What gets wetter as it dries?
I am black white and read all over.
I can run but not walk. Wherever I go thought follows close behind.
If a man carries my burden they will get crushed to death. Though not rich I leave silver in my track.
I fill a room but take no space. What am I?
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
