Answer:
What comes down but never back goes up?
If you drop me I'm sure to crack. But give me a smile and I'll always smile back.
If you have me, you want to tell me. If you tell me, you don't have me.
What comes one time in today, three times in tomorrow and never in the future?
I cannot be felt, seen or touched; Yet I can be found in everybody; My existence is always in debate; Yet there is a style of music named after me.
I touch the Earth, I touch the sky, but if I touch you, you’ll likely die. What am I?
