A B C D E F Gee, What Was I Thinking!?!?

Joe is watching TV so Scar and I are sitting on our bed with a pad of paper and a pencil and I am trying to teach her letters A - G.
She has a book of ABC stuff and we get to letter F and I say "what's that picture of?" and she looks at me
"it keeps us cool in the hot weather" I continue.
More blank looks from her
"it starts with the letter f" I tell her

"It's a faccuum" she informs me.
