Mrs. Cranky makes a sound that is not a word, but is full of meaning.
If said matter-of-factly it means, “So who cares.”
When it is said loudly it means, “I don’t think so.”
When said really loud it means, “You have got to be kidding.”
When said loudly and with attitudinal emphasis it means, “It is not going to happen.”
I don’t know and I don’t want to find out.
