As we were leaving, Henry turned back toward Millie's paddock and yelled, "BYE MILLIE!" and the sweet old donkey brayed back at him.
Made. His. Day.
We also had homemade pizzas and spent the last hour of the evening riding bikes, but by far his favorite part of the day was "talking to Millie."
When I was tucking him in last night he whispered, "Mama, I'm glad today was my birthday. It was the best birthday ever."
Love that guy.
