Griffin's first unprompted meaningful conversation with a friend his age:
Griffin: What you doing?
Griffin: Making letters?
Hannah: No, digging.
(And then he sat down on the riverbank beside her to dig too.)
During that same playgroup, Griffin also did his first spontaneous translation from French to English so a friend could understand what we were talking about:
Maman: Griffin, tu veux jouer à la plage? [Do you want to play on the beach?]
Griffin: I want to jouer à la plage! You want to play in the sand, Loryn?
(Interesting--this shows me that his understanding of the word plage, beach, is that the "sand" idea is more important to him than the "water" idea.)
