Slaps forehead...

I decided this afternoon that I should tell the house insurance company about the impending conservatory and solar panels.
Then had a massive panic because I couldn't find the house insurance paperwork. Found last year's renewal and a letter from from the previous company saying "sorry you're leaving us" but nothing to replace it.
Eventually convinced myself I hadn't renewed it; found a quote from another company with what looked like a good price, but no policy. Rang a nice lady called Lorraine at their call centre - no policy there at all. She quoted me, again a great price, with no extra for the conservatory or the solar panels, and I was all set to pay up...
Then I saw a "new mail" alert in my "only give this to salesmen" hotmail account, which I don't use very much... It was from the motoring organisation who'd provided the car insurance this year... just a newsletter, but I started to wonder... After a bit of digging, I found an email there with all the documents attached for the policy I *had* taken out in August.
Am I going dotty or what?
And how foolish would I have felt if I had taken out another policy when I already had one?
Perhaps I should just retire to a nursing home and take up basket weaving now... not sure I am safe to be let loose with a computer...
