Whose Kid IS He?

On our way to preschool this morning:

N: Mommy, will you go my favorite way? (His favorite way to preschool involves a slight detour, but takes us past train tracks that occasionally have actual cargo trains on them, which is basically a 5-year-old's version of heaven.)
Me: Sure, sweetie.
N: Thank, Mommy. You're very kind.
