My life in a nutshell.

                                      My life in a nutshell.
Story goes that I grow on trees.
People are now allergic to me go figure.
I am usually round and hard to cut open.
You need a nutcracker to crack my shell.
There you will find the prize.
Protein,fat, and carbs.
I don’t know why people use my name now as a definition for crazy people but oh well.
I make candy bars more nutritional.
I’m a good snack as long as you don’t have a reaction
