I want it all
If I cook a 12" pizza in the oven, then I'm going to eat the WHOLE THING in one sitting. Yum! But if somebody else cooks a pizza and serves me just 3 slices of it, then I'll be fine with 3 slices and not need a bite more. I just want to eat everything in front of me. What I can't understand are people who order a plate of food at a restaurant and then leave half of it for the waiter to throw away...I could never do that. It's like I have to eat the entire thing as a matter of principle.
