I grew up and went to school in Northumberland, in the north of England. At school, I was good friends with two girls, Debbie and Morag, who were best friends with each other. I didn't keep in contact with either when I left school and went to University, in Brighton, at the opposite end of the country. Four years later, I started a job in Kingston-upon-Thames, on the west side of London and over 200 miles away from Northumberland, and had forgotten completely about these two girls.
One day, after work, I popped into Sainsbury's in Kingston to get some shopping done.
