Many children are naturally picky eaters. It may even be genetic, or developmental. But given a range of healthy choices, children will choose a balanced diet—so long as junk food isn't included in the mix. Children are tempted by sweets and fried food just as much as we are.

There's a world of difference between, Look at this mess you made! and I don't like to see food on the floor!

The point is that we can't behave right when we don't feel right. And kids can't behave right when they don't feel right. If we don't take care of their feelings first, we have little chance of engaging their cooperation. All we'll have left going for us is our ability to use greater force. And since we'd like to reserve brute force for emergencies such as yanking children out of traffic, we've got to face this feelings thing head-on.

As for logical consequences, the logic is highly debatable. If you continually arrive late for my workshop, despite my warning that lateness is unacceptable, I may find it logical to lock you out of my classroom. Or perhaps it would be more logical to keep you locked in after class for the same number of minutes you were late. Or maybe my logic demands that you miss out on the snacks. As you may be starting to suspect, these are not true exercises in logic. They're really more of a free association, where we try to think of a way to make the wrongdoer suffer. We hope that the suffering will motivate the offender to do better in the future.
