Have you ever protested someone is wrong only to realise it is indeed you that is wrong .

Not long ago my internet stopped after a power cut. I did all the things you are supposed to do, including standing nearly upside down trying to read the password which is a peculiar mix of upper case, lower case letters and numbers. Nope. Nothing worked. In high dudgeon I phoned BT and got a lovely girl from Waterford who talked me through it all. She checked the line was fine. Finally she asked if I had switched it off instead of on. Reader, I didn't even know there was a button to switch it on, and yes, I had inadvertently switched it off while fumbling and muttering dark thoughts. I was embarrassed, she was kind. Which in a way made it worse!

Well I’m not always right

But I’m never (ever) wrong……

There was the time I got someone out to my 'broken' cooker, which was still under guarantee.

The oven wouldn't come on.
The engineer arrived, turned a couple of knobs, or pressed a button or two, and on it came.

It turned out that I had accidently set oven timer function.

I didn't even know it had a timer!
