Kindness
"I didn’t want to bring it up."
"Why not?"
"I didn’t think it was any of my business. I thought it would be rude to mention it. I didn’t know how you’d react."
"Well I wish you had. Because you were too polite to mention it, I’ve been talking to a group of people all evening with spinach between my teeth. Because you didn’t let me know, I’ve been using a word in your language which is crude and offensive and I had no idea. Because you were too chickenshit to stick your head above the parapet, you’ve left me high and dry. Let’s make a deal - the next time you decide to be polite and not to cause a stir, make sure I’m out of the room, will you? Your sort of kindness I don’t need."
