Answer:
What can go up a chimney down but canβt go down a chimney up?
I cannot be felt seen or touched. Yet I can be found in everybody. My existence is always in debate. Yet I have my own style of music.
I am a protector. I sit on a bridge. One person can see right through me while others wonder what I hide.
Where I am there is no south, west, nor east, and weather is not fit for man or beast. What am I?
I get wet when drying. I get dirty when wiping.
No matter how little or how much you use me, you change me every month.
