And then your aforementioned daughter begins behaving strangely. Is she sickening for something? The girl starts insisting that she wants her wedding reception to be held at a hotel, not at your home. Is it just pre-wedding jitters? After all, your home is just as respectable as the groom-to-be's parents' abode. You feel quite hurt.
But then a quick word with your dear, dependable sister reveals all: darling daughter is ashamed of your... er... loo... er... sorry... I mean W.C.
You start sprinkling Harpic round the bowl nightly, and all is well. The reception is a great success.
Problem solved. A happy ending.
Harpic was invented by an Englishman - Harry Pickup of Scarborough - in the 1920s.
