Oblivious Per Usual

Charlie was, as usual, oblivious when I tried to explain to him this morning that we were going on a trip tomorrow:
ME: "Charlie, we're going to get on an airplane tomorrow and go visit Aunt Mandy and Uncle Joel and Cousin Ben and Cousin Rebecca tomorrow, for Thanksgiving."
CHARLIE: (watching tv) "Look at that monkey!"
ME: "So you're not going to school tomorrow; we're going to get up early and go have a fun weekend with your cousins."
CHARLIE: "That monkey's grumpy! Mama look at that grumpy monkey!"
Well, as usual, I tried.
