The Fruity Taste of Life

Sweet and sour is life
What yours shall be, destiny shall contrive
But dependence on destiny shall decrease
And it will then depend on you, my friend decrees

What say you to that?
What surprise can pull from the hat?
Think of the sweet Tangerine
Perhaps you would, the sour Tamarind

They both spell L-I-F-E
For not even in strife
Shall the sweet in Tangerine
Be comparable to the sour in Tamarind
