Beg to differ

Lauren was unloading the dishwasher and noticed it had done a less-than-stellar job getting all those pesky food bits off of the plates.

Sam: I ALWAYS rinse my plate all the way off before I put it in.

Me: Hmm.  Sometimes I do but sometimes I don't. It seems like the dishwasher should be able to handle a little food, though.

Sam: I always do.  I guess my standards of cleanliness are just higher than most people.

{widespread bursting of laughter throughout the kitchen}

Ring-ring!  Hello? Oh, Sam! It's your room. It's calling to BEG TO DIFFER on the standards of cleanliness.

But thank you for the laugh.
