Oh yes the thrill of Mabel's little stamp! I can't see that impressing anybody these days.
Funny how everyone called her Mabel behind her back but wouldn't have dared admit it to her face.
Are you sure it was "come in" and not "enter"? I remember even if the light was on you still weren't supposed to enter until commanded to do so.
Do you remember her opinion of a Lancashire accent? It was all very well to have one just so long as one never used it.
