Answer:
Iām tall when Iām young. Iām short when Iām old. I can light up your world. What am I?
First you see me in the grass dressed in yellow gay; next I am in dainty white, then I fly away. 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?
Though I am only two words I have thousands of letters in me
If you drop me I'm sure to crack. But give me a smile and I'll always smile back.
Give it food and it will live, give it water and it will die.
