“One thing only I know, and that is that I know nothing.” – Socrates.

Being the parent of a teenager certainly keeps you 'real'. There was a time in my 20s and 30s when I thought  that I was reasonably intelligent with a fairly wide general knowledge. There was a time when my children were little that they looked up to me and trusted me to answer all their questions, but now they treat me as if I know nothing. My son is always keen to share his 'vast knowledge of life' accumulated over 17 years! To be fair he does have a wide general knowledge, but like most young people he only sees things in black and white, he will need to notch up a few more years before he starts to see shades of grey and then he will gradually realise how much he doesn't know. Until then he is content to tease me abort my astounding ignorance. I am not very good at sitting still and I have never been terribly interested in films and television and with one or two notable exceptions I have no interest whatsoever in sport so it is hardly surprising that I do not know the names of actors or sports personalities. Not so long ago my son decided to test me to find out exactly how challenged I am when it comes to knowing who does what. The whole family roared with laughter when I though that George Clooney could be a golfer, apparently he is an actor. I don't mind the teasing, after all if we did a similar test on history, poetry, literature or various other things I am fairly sure that I would know more than them!

Recently I encountered a woman who told me that she intended to return the game that she had bought for £32.99 the previous day because it was not fit for purpose. I asked what was wrong with it and she said that the questions were much to hard (the game was age 12 to adult). I must have looked a bit sceptical because she told me what some of the questions were.

- Who was Nebuchadnezzar

- What is an archipelago

- Who was Samuel Pepys

I was able to answer all the questions so she posed a few more which I also answered correctly. It was probably just luck that she chose questions that I was able to answer, but I was deeply offended when she told me that I only knew the answers because I am old! I thought (but didn't say) that old or not, I would not wish to publicise my ignorance by returning a game because it was too difficult! Maybe I am old, but I like to think that I could answer the questions because I have a wide general knowledge and I had a good education.

These little episodes along with the start of an annual recruitment phase at the company I work for has led me to realise that it takes all sorts to make a world - and it takes all sorts to make a good workforce. A group of people with different and complementary skills (and personalities) will make a stronger and more competent workforce. Only a fool appoints in his/her own image.
