MATIAS.- From Franklin to his buddy

Dear Thomas:
I'm wriring you because I need some help. I realise you are my best friend and the only one I can really trust.
These days have been terribly for me ,specially because some people want to kill me, you know? The point is I've written several important letters about France and they are absolutely valuable.
Please!!, could you copy them and keep them in the safest place you can imagine? I mean ,they can change the future of our nation.
I would be grateful if you could do it. By the way you will be always remembered in the United States history.
On the other hand ,I've finished my first odometer and I want to give it to you as a gift.I appreciate your help and advice. You are a great team-mate.
Fighting this war is very hard for me although sharing this time with you, lets me carry on.
Hugging you with best of regards,
Benjamin Button

P.S. Button is my real sirname ,though Franklin is the sirname of my uncle.(TOP SECRET)
P.S. 2 I'll never forget when you discovered the lighting rod, your support incredibly useful.
