When my in-laws come over to babysit they’re always washing my dishes for me.  Except, even though we have a perfectly good dishwasher, they wash them all by hand.  I really wish they would stop.  I’m sorry, I just don’t trust that everything is sanitized properly.  But how do you tell someone, “Please stop being nice because I don’t think you’re doing it right,” or even, “Your helpfulness is giving me the willies,”?                – wg
