Have a good noon we will!

Elisabeth has picked up on the fact that when we part from friends, we often say,

"Have a good ___ (afternoon, evening, etc.)"

She has also realized that the other person usually says, "We will."
So now whenever we part from someone, she does the whole thing herself (except for the "after" part of "afternoon"). In parting, she says,

"Have a good noon we will!"

and bursts into laughter (because we do).
