Answer:
What can travel around the world while staying in a corner?
You can see me in water, but I never get wet. What am I?
I tell people to be careful when handling boxes.
I am in the past never in the future. I don't exist but have existed. I saw what you saw and that is what I will ever see.
I can be written, I can be spoken, I can be exposed, I can be broken. What am I?
What never gets any wetter no matter how hard it rains?
