The deal was, that they had to complete the chore before they could have dinner. Brooklyn immediately began to whine "why do you make us work so much?". My responses are usually something like "Because I am a mean mom who loves to torture her kids." or "I love to pretend like I am Miss Hannigan, and you are my orphans and have you to clean the whole house".
Foote on the other hand trys to take the loving approach and help them realize the benefit of respondsibilities. At dinner Foote asks Brooklyn " When you grow up an have a house do you think you will want your house to be clean or dirty?" Brookie replied "Clean." Foote - "Will you want your house vacuumed?", Brookie - "yes" Foote - "How will you know how to vacume your house if you never practice." long pause Brookie -"Well, when I was at Grandma's house, she told Ann how to vacuum in a straight line and I was listening to her, so I know how to vacuum." Foote - "Don't you think you will need to practice" Brookie - "No I was listening so, I will just remember." Leave it up to brook to justify herself out of chores.
