Answer:
I am the thing that is used to make your weight. What am I?
When you stop and look, you can always see me. If you try to touch, you cannot feel me. I cannot move, but as you near me, I will move away from you. What am I?
I can be repeated but rarely in the same way. I can't be changed but can be rewritten. I can be passed down, but should not be forgotten. What am I?
You seek me out when your hunger's ripe. I sit on four legs and smoke a pipe.
I store fire-breathing animals.
No matter how little or how much you use me, you change me every month.
