Meal planning conversation

Me: Ok if we want to eat at 6.30pm what time do the potatoes need to go on?
D: Meat first.
Me: Yes, what time for that?
D: Count back.
Me: Can you write me out a list...You'll put the meat on the spit at at blah blah; I'll attend to the chicken at blah blah; potatoes ...
D: Yes of course.

Result.
(PS I got a proper list once we'd had a laugh)
