1. A time when they are green a time when they are brown.
But both of these times cause me to frown.
But just in between for a very short while they are perfect and yellow and cause me to smile!
What am I talking about here?
2. I never was, am always to be,
No one ever saw me, nor ever will
And yet I am the confidence of all
To live and breathe on this terrestrial ball.
3. Only one color, but not one size,
Stuck at the bottom, yet easily flies.
Present in sun, but not in rain,
Doing no harm, and feeling no pain.
What is it.
