Answer:
What goes up and down stairs without moving?
I am a pretty one, fluttering in the pale blue sky. Delicate, fragile on the wing, indeed I am a pretty thing. What am I?
I am just two and two. I am hot. I am cold. I am the parent of numbers that cannot be told. I am a gift beyond measure, a matter of course. What am I?
I can never be stolen from you. I am owned by everyone. Some have more some have less.
I am orange and sound like a parrot.
I am used for light yet I am solid. Without me you would feel enclosed. I hate being touched especially with a lot of force. I like to be in buildings.
