I need to apologise for the thing I said about elephants earlier - I should have said blind
-folded folk.
It was something that cropped up when I was still at school, to show us how words can be inadequate to describesomething, especially of you do not have access to all the information.
But the words used, at the time, were both sexist and able-ist.
I did remember to change the sexist word, but not the able-ist one. Very sorry.
