The best I can do.

Dear Mario, I am sorry that you ended up in prison. I would be planting my tomatoes now, but I am too old to turn the patch of ground out back to put the plants in. Hope you are doing good. Love, Your Father
Dear Dad, Don't dig in that patch out back, cause that's where I buried the bodies. Love, Mario
A few days later the Police showed up and started digging up the old man's back yard. They dug up the whole place, but didn't find anything.
Dear Dad, That's the best I can do for now. Hope your plants have lots of tomatoes. Love, Mario
