Deciphering Toddler

Ryan has hit an age where he tries to tell stories. It's very entertaining because he doesn't always have the language to say what he wants and even if he does you can't always understand the words.
Today he was telling us that he wanted Grandpa to visit. His story went like this "Pa, Ryan" "Pa Truck outside" "Pa Up" Which essentially means (it takes a parent to understand.. and even then we rely somewhat on hand motions)
"Grandpa is going to come see Ryan, he will drive his truck and park it in the driveway and he will pick up/ carry Ryan."

Ryan thinks it's hilarious (most of the time) when you guess what he is saying... he will laugh and laugh until you get it right, then he will say "Yes!" as if it was the most obvious thing in the world.
