Standing on my own two feet

A few weeks ago I got this card..

from the blood service thanking me for donating 3 times over twelve months, and with it came a letter saying I can claim a slate coaster next time I give blood which was to be Tuesday 5th November.

I always go with my dad in fact he 'always' does the booking up for us, but this time dad would not be coming as he is unable to give blood anymore.
I felt quite emotional when they asked where my dad was as they noticed he had canceled and thought he had gone on holiday again, as he is always nipping off in his caravan, lol. So it was a little upsetting telling them, that he is unable to give anymore, they were really sweet, gave me a slate coaster for him, but it was the thank you card that they went and wrote out that really touched a nerve, thanking him for the 109 pints he has donated, (makes my 35 look a little feeble, lol) and that was not counting the pints he gave when he was in the Army.

He was taken back by the card and coaster when I gave them to him, as he was a little disappointed having to stop, as he always thought he would get to his 70th Birthday (which is the age you have to stop), so he still had 2 years to go, as he's still a spring chicken at 68, lol.
This is my coaster...

So now my daddy's not coming with me anymore, I really got to learn to stand on my own 2 feet, so I had to make my next appointment all by myself while I was there, lol

So can someone please remind me nearer the time, that I'm next giving blood on the 17th March 2009, as I might forget, as dad always reminded me when it was due...
