Another Gracism

She was doing a great job on the toilet, our conversation was as follows:

Grace: "Pffffffffft"
Grace: "I tooted, excuse me."
Me: "Good girl! But you don't neccessarily have to excuse yourself when you are on the toilet, Grace."
Grace: "Yes, I do!"
Me: "Suit yourself."
(after a brief pause...)
Grace: "I already tooted." (she must have heard me say "Toot" instead of "suit")
