A bluebell seemed somehow fitting for Doris.

When I was in my late 20s I had a job which required me to travel a bit. One summer evening I gave a male colleague in his early 60s a lift from Berwick to Wooler. I always carried a Doris cassette in the car. We were both avid fans. We sang all the way. Stretching the generations.
I thank her for that evening. 
And the pleasure of sharing her birthday every year. I would buy cakes for Doris and not me. I think I still will.
