Idiot!

Technical brilliance just cost me £20.

This wireless mouse, no it does not act like a wireless, this mouse ceased working.  It had fallen upon the floor for no good reason a day or so before and I worried it may be wonky.  However, I changed the battery, I had three lying on the mantlepiece doing nothing, put one in to discover this did not work.

The brute lit up and went off again.  Most annoying.  So I tried the other batteries, same result.  It is either broke or the battery is dead.  I had no more batteries, bar one.  This I took from elsewhere and inserted it into the mouse.  Same result.  Nothing for it but to obtain new batteries anyway and order a working mouse.

Several long days later it arrived, at 7 pm in the evening!  Royal Mail parcels are being delivered at all times, and on a 7 day rota at that.  No wonder smiling posties are hard to find these days.  Long hours, no extra pay, bad management, increased prices and appalling delivery ideas, all this to line the pockets of the few while the service deteriorates.  I support the postmen, not the owners.

Anyway, I got the new mouse, fixed it up with a new battery and put it to work, success! 

I had faith this would work!

However, I then tried one of my new, new batteries straight from the shop in the old, broken mouse.  This is an attempt that must be tried, and of course it worked first time!

So, tech marvel me spent £20 on a new mouse when all I required was a new working battery.  

I do not come from a family of engineers...
