The Tree, Grapes and Me

I saw the tree
The grapes were far
I didn't jump
I couldn't have reached
I declared them sour
Today, I ponder to myself
Why didn't I jump?
What if I could have reached?
Probably I would not have
But I didn't try
And therein lies the rub
I don't see the tree now
Grapes are gone along with the tree
Not everyone gets a second chance
Yet I fear finding the tree
More than I fear not finding it
If I jump and I don't get
The grapes will really turn sour
Imagination will turn into reality
Maybe I am running from the tree
Searching it may just be a pretext
I don't know
I am helpless
Why did I see the tree in the first place?
