If you need to jump your car, you do NOT hook up the leads backwards. If you have batteries in your camera or flash, they don’t work if they are not positioned correctly. There is a definite difference between positive and negative. Yet, I was talking to a receptionist today and we stumbled into a phrasing swamp. I mentioned to her that I had heard mum’s biopsy report was positive, which is a negative thing. Yet, if it had been negative, that would have been a positive. So, it was bad that it was good??? How on EARTH did language jump from positive and negative being well, good or bad to mixing them up?????
This tune from ‘My Fair Lady’, doesn’t really have much to do with the oddity of positive and negative, but it is great fun!
