When I came back from work the other day and went to finish my mid-morning tea, I discovered that the mug had somehow cracked. It was fine when I left it. I guess some "crack elves" were at work while I was teaching and shopping.
Now I'm down to one and will have to buy a couple of new ones. This does happen periodically. But it has never happened quite like this.
Kapora! Better the mug than health!!
