OK, don't get me wrong, I know that temporary traffic lights are a great invention - they stop people crashing into holes in the road that have been dug so that our drains etc can be fixed. They also help to prevent games of chicken when part of a road has been blocked off for some reason.
But why were those lights there? There was no hole! There was no digger waiting for tomorrow's digging! There wasn't even a pile of pipes waiting to be connected to the sewage system, eager to transport our bodily waste to the treatment centre! In fact the protected section of road was in immaculate condition. Perhaps this is a new way of stopping our roads wearing out so quickly?
Anyway so there were the lights in all their glory, guiding the traffic around a perfectly clear section of road. But you forgot one thing.
Can you remember what you forgot to do before you went home for dinner?
I am sure you can if you think hard enough.
No? Well I will tell you then.
You forgot to tell them that they should change colour from time to time - they don't work properly when set permanently to RED!
