I’ve just read in “The Week” (9 April) that it’s been claimed that having two daughters is the key to a happy life. According to research, ” … two daughters get on well with each other and with their parents …”

All I can add is that I hope they didn’t spend too much money on this research because I could have given them the information free of charge, based admittedly on a very small sample.

I am a very happy man. I have two daughters. QED.

My two daughters are quite different in temperament and talents and have followed qute different paths – one a junior doctor, one an actor and singer – but they not only get on well; each is the other’s biggest fan (biggest fan after me, that is).  I rest my case.
