I have no idea what happened here. All I know is that we brought him home from the hospital like a week ago, and tonight we had his Kindergarten open house.
He met his teacher (for the second time, actually), he explored his classroom, he met some of his new friends, he petted a gecko, he located his cubby....
His first day of Kindergarten is next Tuesday.
And the following week he'll be graduating from high school.
