The same battle is waged every single evening at my sister's house...
The Battle of the Dishwasher
A.k.a. The only real chore my 17 and 13 year old nephews have to do round the house (why yes this does bug me, how could you tell?)
Despite it being a task they can absolutely rely on to happen every day, they repeatedly have to be asked to empty and refill the dishwasher after every meal and the same amount of sighing and general slothness of movement is acted out each time.
They've managed to turn this relatively simple task into the most complicated dance around the kitchen you've ever seen. It takes 5 times longer than anyone else would take to empty it and results in 5 times the damage done to the crockery.
Every so often the eldest nephew trots out the same old sob story, pointing at his younger brother, "He owes me. I had to unload the dishwasher by myself for 6 weeks when he broke his arm"
My usual response is something along the lines of "And pray tell how did you make it through such a trying time in your life?" But the other day I tried another tack...
"Well in a year's time you will leave to go to uni and your brother will have 4 long years of unloading the dishwasher ahead of him."
"No no it won't even it out," snorted my nephew derisively in that manner that teenagers have that makes you want to beat them round the head with a wet sponge, "because I'll be unloading my own dishwasher at uni."
I never heard if he said anything else, I was too busy cackling and repeating "A dishwasher at uni?!" and rolling around on the floor...
