The way i understand this is that you tell your 3 kids that you have a
Burger King combo meal. But you don't tell them that the fries in your
right pocket, the coke is in your left pocket and the burger is in your back
pocket. This is suboptimal since your oldest prefer the burger and he might
have to search all the places for it. Same argument goes for the other 2
kids. This takes care of paragraph one.
Paragraph 2, you tell your kids where each item is located at, but it's
complex because maybe your right pocket means left to your kids...etc :)
Ugh, lunch time :)
