:-) Ok so it's not really a grudge.
Sometime in 1958 I had my tonsils removed. It's so long ago I really don't remember if it was painful or not; it probably was. Anyway, the nurse in the childrens ward promised me that if I was a good boy and didn't cry she'd bring me some icecream. I was a good boy - I didn't cry. And I'm still waiting for that icecream!
