Sam's Life Lessons

Recently, Sam has experienced an enormous outpouring of spelling and writing. He wants to know how any word he's never encountered before is constructed. He wants to understand the finer points of sentence structure. And he's even started writing, so every project that comes home from school bears the stamp: "To Mom, from Sam." (yes, I never get the love in these scenarios)

I attribute this outpouring to a late Christmas gift of the LeapFrog Word Whammer, a jet-shaped magnet for your refrigerator that allows you to create 3-letter words and have them spelled and said back to you. While Noah loves the toy because it plays the Alphabet song and he can sing along (though he tends to get stuck at E and just hold the vowel for a very long time), Sam loves that it has upper- and lowercase letters and allows him to create massive sentences in our kitchen. One night a few weeks ago, I came downstairs after putting Sam to bed and found this on our fridge:
I pondered over the meaning for quite some time, trying to figure out if Sam was thinking of a recent time we went out to eat or if he had a more existential meaning, some important life lesson he needed to share but was interrupted by bath time. My curiosity only grew the next morning when I was making breakfast and Sam marched over to his letters and added three more:
(in this one you can see the Word Whammer itself) Evidently, whatever his tip was, it shrunk in the night. Any guesses as to Sam's obscure meanings?
