Not the kind of maturity that you say like this:
Mr. P and the College Kid got into a discussion on whether the snake I saw last week was a rattle snake or a rat snake while we were at family dinner last night. In a stand of supremacy, the College Kid went out to the car and got her notebook for the critter class she is taking (all things reptilian and amphibious I want to say) to demonstrate her classification and naming prowess. After her asking me a few questions about that snake's head where I might have made up the answers she admitted it might be a rat snake (she was on the side of rattler) and decided to go play with Eli in the kid's play area of the restaurant.
While she was gone I grabbed her notebook and we added stickers and other commentary to her notes. For example, Penny wrote "I HEART PBI" which stands for some sort of breeding, but I don't remember what the P or I stands for now. Teddy wrote "I heart NEWTS" in SororityGirl16 font. Mom had some stickers with snakes that we added to her notes. But the piece de resistance that had me laughing SO hard that I cried and then my throat got all phlegmy and thick?
Which if you don't know what it is, it is Mr. P's rendition of the SNL skit baby hands lady which comes up in many a family meeting...see the tiny hands on the star stickers????
Like I said, we are MATOUR.
