Answer:
People make me, save me, change me, and raise me. What am I?
What gets broken without being held?
I can swim but never get wet. I can run but never get tired. I follow you everywhere but never say a word.
What has keys but no locks a space but no room and you can enter but can't go in?
I am seen in the water. If seen in the sky I am in the rainbow a jay's feather and lapis lazuli.
No matter how little or how much you use me, you change me every month.
