young and sweet
When young I am sweet in the sun. When middle-aged I make you gay. When old I am valued more than ever
A time when they?re green,
A time when they?re green, a time when they?re brown,
But both of these times, cause me to frown.
But just in between, for a very short while,
They?re perfect and yellow, and cause me to smile!
What am I talking about here?
