Call in Sherlock Holmes please

I heard from Papworth today...Yay! I need to do another test...Boo! But I will lay back and smile widely while thinking of England or in my case...Papworth, as yep you guessed it, this test is another smear.
Apparently my last smear was done in 2005, which means I've been on oxygen longer than I thought if my surgery is correct?
Now I've been working it out.
I know that I have only lived here in my bungalow for the past two and a half years now, this being my third Christmas. Plus I had only lived in my cottage at Braintree for two and half years, that making five years. I know for sure that I had just been put on oxygen when living at Braintree when I had my last smear, as they had to put me on oxygen kicking and screaming, as I was so against going on it.
My poor physios certainly earned their wages then, as I was throwing my toys out the pram in a tantrum left right and centre!
I was so convinced that I was correct and I was so annoyed that my surgery had told Papworth that I had never replied to the letter of invitation to have a smear, that I went through my own personal file of doctors letters and guess what? I found a letter from my specialist to my surgery, stating that I would benefit from long term oxygen therapy at home...dated 13 Dec 2006, meaning that I started my oxygen in 2007.
2007 from 2011 is 4 years even with my crap maths.
Ok so what has gone wrong here then? Surgery sent the wrong dates or put wrong dates on my file?
I understand Papworth wanting to get everything exactly right, which I am jolly pleased about as after all it's my life in their hands, but it looks like my surgery hasn't quite got it right and that's scary. At first I was annoyed that this blunder will hold me up going active, but now I'm just worried that they had got it wrong in the first place, so what has happened to those results of 2007?
Although I'm still furious that they said that I hadn't replied to my smear invite and this will be made known when I go on Thursday morning, because when it comes to my health I am diligent to the extreme....Grrrrrr... I won't be grouchy or rude as that isn't my style, after all everybody makes mistakes, but why say that it was my fault for ignoring the letter (which I sincerely doubt there was one) and not going for another smear?
As Jean has always said, I never forget if I have been wronged.
I will wait till after the smear has been taken, as I don't want the nurse taking at a run at my vagina with the implements and I will wait till after she has put urgent on the sample request form and then I will ask why the dates given to Papworth were different to what I know, as after all I was there, legs a kimbo, smiling widely!
Blimey I can't wait till Thursday now.

Lots of love Debbie x
