Changed dimensions

Robbie has bought a new mug, and he spent most of Saturday evening holding out his mug for me to admire. It is a very nice mug (it should be at the price he paid for it!) but I can't get excited about a mug. On Sunday morning he sat down next to me to have a serious chat, he said he had measured the capacity of the new mug and as it takes more coffee he will require more sweeteners. He now requires two and a half sweeteners! I will not repeat my response in detail but I left him in no doubt that I have better things to do with my life than cutting sweeteners in half!!
