The first time someone asked me to be their mentor, I was both flattered and puzzled.
It felt like an honour to have been asked, but I wasn’t quite clear about what being a mentor actually meant. Instinctively I turned to the dictionary, and in doing so realised that I was consulting a mentor of my own.
Although it’s called the Shorter Oxford English Dictionary, it comes in two hefty volumes, runs to 2,672 pages in my edition, and weighs in at 4.6 kg (I know, because I’ve just weighed it on the bathroom scales.) I bought it more than forty years ago and ever since it has been on hand, always beside me in my office, ready to be consulted if I need it.
