Letter: Many a slip 'twixt the cup and the lip

Sir: The belief cited by Alec Just (Letters, 29 May), that we are always aware of the undrunk coffee remaining in a mug, can lead to some of life's bitterest disappointments.

We must all have experienced at some time the desolation felt on discovering, when preparing for one last delicious gulp, that the mug is already empty. Conversely, there's that pang of regret which strikes when we pick up an "empty" mug to take into the kitchen, only to discover an inch of cold and now undrinkable liquid at the bottom.
