It was a Christmas present from my auntie and features a cartoon cat with the legend 'Alice is Purrfect'.
I've owned it for years and taken it to every full-time job I've had. It's always been my work mug because it has my name on, so nobody can pinch it unless I have the misfortune to work somewhere with more than one Alice. I have probably drunk more coffee from it than from all the other mugs I own combined.
I have zillions of mugs at home, of course, largely underworked layabouts. Tonight I will pick a sturdy-looking example to face the rigours of the working day with me.
