I remember you mentioning in the distant past, that you had gone to Culcheth Hall, did it stop you fidgeting? I'll look at the Sale Grammar website, I might find a photo of my husband and his brothers, none of whom were there at the same time. His half brother was there for 5 years, then his brother was there for 5 years, then my husband went and was there for 7 years (through the upper 6th).
As you are 2 years younger than me, I wonder if you knew Geraldine L******, who lived in Lymm, she was the sister of my best friend. I've not put her full name as I imagine she is still alive, but I'm sure there were not many Geraldines. Is your friend Joan the same age as you, I can't remember any Joan's in my school year.
