Teen Cleaning Priorities

My sixteen year old has responsibility for the dishes in our house and we have quite the difference in opinion about what qualifies as a clean dish.

I've seen enough sparkling dishes in my life to know what a clean dish looks like - but apparently he needs his eyesight checked. I don't argue with him anymore, I just put the dish back in the sink. I figure that he'll get tired of washing dishes over eventually, right?

Then today in the car he was polishing his iPod with great care and lamenting the slightest smudge. I asked him why it was that he couldn't see soap scum on a bowl - yet he could notice the tiniest smear on the face of his mp3 player.

'Well, I'm not going to watch my podcasts in a bowl am I?'
