not a Gator, a Matthew

Matthew just came and told me good night. It goes like this:

Him: I need to tell mommy.
Me: Okay, come tell me.
Him: Okay, goodnight mommy.
Me: Goodnight, darling.
Him: I need to go tell daddy.
Me: Okay, go tell daddy.
Him: Okay, night night, see you later.
Me: (chuckling) Okay, see you later-Gator.
Him: See you later MATTHEW.
Me: Oh. See you later Matthew.
Him: Night Mommy. (and scampers off for daddy.)
