As a kid, I used to believe that nothing was wasted if you made it a sacrifice to God. So when my parents would pack me a nasty sandwich that I didn't feel like eating, I would silently say "Dear God, please accept my humble sacrifice" and throw the sandwich away. That way I didn't feel bad about wasting food.
