* Closure is like a candy factory
* You send the factory an order to make candies for you with your favorite flavor.
* The factory will pick the right expert for you,
* And it send back to you an expert's contact.
* Now whenever you need, you just call and submit the quantity.
* That expert will take care all the rest for you.

// Now the factory keeps your flavor and your expert.
// In conclusion:
// Only the inner function can access outer function'scope.
// Only the factory can directly tell the expert what to do.
