Along with all of those changes, I am also seeing a deepening maturity in his behavior and actions toward others. He is becoming more respectful, thoughtful and selfless. He is gentler with his siblings and helps out more without being asked. We are also able to have those deeper discussions with him that we've enjoyed with our daughter for awhile now. He gets sarcasm and subtle humor. It's fun to connect with him on this level.
But he's not quite on the verge of adulthood just yet. He still loves to make up crazy names for his siblings, speak in his own dialect of the English language (or sometimes in his raging Frenchman accent), blast out 80's music from his spotify list (he is my son, after all!), play video games and make stop-motion movies, and wield his sword during battles in the yard with his brothers.
I'd say this is a good age for my boy. One foot in little-boy, the other in teenager. He's able to be mature one minute and silly the next. I am anxious to see the young man of whom we are getting glimpses begin to emerge over the coming years!

we find the delightful creature of a boy"
