Retired teachers

Does that include Mr Nichols (IT 'teacher') or was he fired?

"The Scottish phone book is this thick [indicates that the book is slim with his hands] for an area this big [indicating large area with hands}, whereas the London phone book is this thick [indicating a large, thick book with his hands] for an area this big [indicating a small area]. That is what a computer file sysytem is like".... All I learnt from Mr Nichols in a year... Thank heavens for Mr Gray and Saltash cruiser cluib spreadsheets...
