You used to come to me for all sorts of information and knowledge before the internet was born
You see a boat filled with people. It has not sunk but when you look again you don't see a single person on the boat. Why?
I always murmur but never talk. Always run but never walk. I have a bed but never sleep, have a mouth but never speak. What am I?
There's not a kingdom on the earth I haven't traveled over and over and though I know not whence my birth yet when I come you know my roar. I through the town do take my flight and through the fields and meadows green and whether it be day or night I neither am nor can be seen.
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?
No matter how little or how much you use me, you change me every month.
