Who can forget their schooldays - whether the best days of your life or not?
The parquet flooring, high windows and seemingly endless corridors. Your friends, foes - and favourite teachers. Your pencil case, satchel and scribbled-on jotter.
And remember those school-calls on the radio too as you dashed for the bus?
Graham Dene recreates that morning moment on Boom Breakfast each weekday at around 7.40.
Let him know where you went and we'll put your school on our map below!
Let him know too of your most vivid memories - and your old friends. The old crowd may well be listening in too.
(Thanks to Boom listener Elizabeth Festorazzi for the great pic!)
