How many phone numbers can you still remember without looking them up and what are they for?
I’ve got 4:
Mum & Dad’s house
Our old house in Portsmouth (we moved out in 1993)
Hendon Football Club’s old number at Claremont Road.
This can be banal too for the rest of the dayshift if you want to go off topic. RTF is not compulsory.
