Hmm well let's see.
He tried to help once by putting dishwashing soap (Dawn) in the dishwasher. I came home to a 6 foot high wall of suds.
My 40-year-old cutting board started splintering in the center (where you make the most cuts), so I asked him to sand it down for me. He sanded it. Then he gave it several coats of polyurethane.
He has, on multiple occasions, crashed his remote-controlled helicopter into my flower beds and chopped them all to pieces.
Fortunately, about the time I start fantasizing about killing him, he either does something super sweet for me, or he goes on a business trip.
