Do you have kids? I always had the same opinion until I had my daughter, and then all of a sudden there is a 2 year old who needs supervision and it becomes easier to clean up after bed time.
Procrastinating and having your attention pulled in multiple places are two different problems. You acknowledge it's easier and want to do the dishes immediately. But when you realize your two year old is painting the walls with poop or filled the toilet with all the toilet paper and tried flushing, resulting in a flood... Everyone can agree, that takes slightly more precedence than dishes.
