Our oldest son was recently assigned the chore of unloading the dishwasher. I prefer to wash dishes by hand and them place them in the dishwasher to rinse and dry. Yesterday he procrastinated about unloading the dishwasher, which prevented me from loading dirty plates and cutlery. My son didn't "realize" that he had not unloaded the dishwasher, even though I had reminded him two or three times that he need to unload, so that I could load the dirty dishes, until after nine o clock. By this time I was preparing for bed, and was not going to wash dishes. My son's consequence for not unloading the dishwasher was that he also had to load the dirty dishes.
Oh, I forgot to add the most important part. We have exactly 8 forks in the house, and all were dirty at dinner time. All the salad plates were also dirty. My son was able to see first hand what happens when individuals in the home don't do their part.
This morning I walked downstairs to a clean kitchen and clean dishes. Hopefully he has "learned" his lesson, but if not another meal time or two without clean plates or utensils will reinforce the lesson.
