Why I Love Peace Corps*, #1:
You can use children as free labor to decorate your house.
In a matter of an hour and a half tonight I had an entire wall covered in charming drawings, and all I had to do was give them scrap paper and put up with a little bit of screaming. Felices as we say here. For that matter, you can ask these kids to sweep your house, mop the floors, wash the windows, fold your clothes, and do the dishes and they will do it. Some will even think it's fun before a more lazy/rowdy kid in the bunch points out that, hey, if we were doing this in our own houses right now it would probably be considered work. But I try to draw a line somewhere.
*I should specify off-the-bat that some of these reasons will be more specific to "why I love living in a small Mayan town in the highlands of Guatemala for two years", however Peace Corps is one of few opportunities that ever would have allowed me to do that, and certainly was the most accessible opportunity.
