One of my favorite little games to play with people who think that words don’t matter is to ask them to replace the word “R” word with the “N” word. “Your daughter won’t remember to take her medication because she’s a [“N” word],” doesn’t quite seem as acceptable for a doctor to tell a parent, does it?
