Never to old Charlie and the chocolate factory fan fic)

"Dad I am to old to be going with Charlie to a silly old chocolate factory!" I knew I really wanted to go but, I was to nervous and mad that I wanted to go to my competitor in the business. "Katie you are not too old Mr,Wonka is the same age you are twenty five and he owns what you called a silly old factory. Also Katie if you haven't noticed you own a silly old factory yourself!" I look down in pity knowing what I said was rude and silly . He smiles and kisses my shoulder and says "Your never to old!"

I do NOT own "Charlie and the chocolate factory" I only own Katie and I only own the plot!

Here's more in detail about the story line!
Charlie wants his sister that has come back into town to go to the factory with her but, she is in the business of candy herself. Her company is a competitor with Wonka. She feels to old to be doing such "Nonsense" when its unprofessional. At first Wonka wants her out because she's a "spy" when really he finds her fairly pretty. However she stays and love begins to grow. However the one question stays in there minds threw the whole tour aren't we "to old?"
