Dishwasher Dad

I had a very rough morning. When the coffee was done brewing I grabbed a mug from the cupboard but it had stuff caked on the inside of it so I had to put it back. It gets rougher. The next cup I tried also had little particles stuck to the inside. Put it back. Tried again. It wasn't until the fourth cup that I found one clean enough to drink from.
        Later I asked my dad what the deal was with the dishwasher not doing its job. He told me that he tends to think of the dishwasher as a sanitizer and suggested me doing as much of the cleaning as possible before putting the dishes in. In a lot of ways I am a carbon copy of my dad and I gladly admire many of the similarities but two dishwashing techniques diverged in a  yellow wood and I being one washer chose the one where I didn't have to do as much work.
        I explained to my dad that I viewed the dishwasher more like an old friend. An old friend that owed me an enormous debt. I don't want this debt to get in the way of our friendship, so I strike a deal. I offer to forgive my friend the debt he owes in exchange for cleaning my dishes. He doesn't get a free pass but it's severely discounted. For the sake of my friend's dignity, I tell my dad, I don't clean the dishes off before I put them in. Go back on my deal? Dilute mercy? No, I am afraid this would deeply offend it.
