I am naturally positive. My instinct is always to see the best out of everything and to look for opportunities in adversity. Indeed, when I was working I would sometimes be criticised because I would not spend enough time on “what went wrong?” because I was always looking for “what can we do now?”.

But even positive people occasionally have bad days, and Wednesday was one of them for me.

Two things went badly wrong. The first was the dentist. I had an appointment for a crown replacement, but my new dentist took one look and told me I have bigger problems. Apparently I grind my teeth at night and they have worn down to a level where the back teeth are rubbing against each other and putting pressure on the side of the crown which was why it had split off. Fixing could cost thousands of pounds which I don’t have. In the meantime he put in a temporary crown and left me in a lot of pain as the anaesthetic wore off.

Then just as I was feeling down, my phone rang. It was the couple who are buying our house. At least they were. Their buyer had just fallen through so while they still want our house, our planned date of March 22nd is now impossible, which means the house we were buying in Lancashire is also off.

So no house and in pain. Not my best day. Mandy also understandably angry and upset. So what to do?

Normally my response would be to switch on my positive energy and find five great reasons to be happy about the day. It would probably have irritated all those around me but it would have made me feel good. But for once it was not what I wanted to do. I just wanted to wallow in my miserableness. I found a quite corner and read a book.

So now it is two days later and and I am very much back to myself. There are lots of good things that will come out of this. My teeth are fine – for now at least. We get to stay in Scotland longer. I will even get my 60th birthday Scottish bus pass. And if the Lancashire house falls through, there will be another one, Fate is our friend.

I have also decided – sometimes even the most positive of people is allowed a bad day.
