I would have been inclined to have responded:
"You won't tell your kids "No!"???
"I See. Well, I hate to inform you, but you will be telling them NO! At the rate you are going, you will begin to tell them NO when your money for lawyers to keep them out of prison has run out and you have to say, No, I can't, I don't have any more money and mom and I have had to move into government housing."
If memory serves me...I laughed when they said it...and told them good luck..!! They had two boys....and probably wore out the word "no"...LOL!!!
