So, say someone (let's call them C1) wanted another someone (C3) to take out the trash. That pesky prefrontal cortex might cause C3 to yell, "Yeah, right!", and other phrases stating the unlikeliness of the trash being taken out. Selfish? One member of the household (C1) may have the goal of goofing off as long as possible. That same person would then write a blog post or surf the interwebsto avoid doing anything that might be construed as housework. Of course, when the person desiring a more tidy house (C2) expresses displeasure at the lack of domestic progress, the person who chose to spend time doing alternative activities (C1) may view C2's reaction as selfish. Let's say that a request was made by C1 - that maybe another Cleaver (C2) could start a load of laundry while C1 was at work. Imagine C1's surprise to see that, indeed, laundry was put into the washer. Yippee!
