I am so going to steal this line the next time Roger and I have an argument. Humour diffuses things like nothing else can. We had a row recently where I got testy because I'd just spilt something in the fridge and was getting a cloth to wipe it up. "You've spilt something in the fridge", he felt the need to say. Me: (very testily): I KNOW! I'm cleaning it up now!"

His response: "Well, I thought I'd better tell you because I wasn't sure you were tall enough to see."
