Everybody knows a Sally Metcalfe. She's the neighbour whose curtains are constantly twitching, desperate to stay one step ahead of the others whilst secretly yearning to fit in.
That's probably one of the reasons Sally has become such a national treasure, and today marks 30 years since she first appeared on our screens.
Corrie is at its best when the characters drive its storylines, and although the soap is a completely different beast to what it was three decades ago, the character of Sally has remained strong and relatable throughout. That's not to say she hasn't changed - the snobby social climber we see today is a far cry from the tomboyish teenager we saw shouting at Kevin for splashing those god-awful PVC boots in her very first scene.
The character of Sally has been through everything from affairs and failed marriages to cat fights and cancer. Her living room has seen more drama than the Royal National Theatre, and I'd be surprised if Rosie and Sophie still have hands thanks to being banished upstairs to wash them every time an argument broke out.
Who could forget the iconic catfight in 1997, when a double-denim clad Sally wrestled Natalie Horrocks to the floor? Or this powerful scene from the live 50th anniversary episode, in which Sally discovered Kevin was the father of Molly's child?
Sally Dynevor, the actress who plays Sally Metcalfe, has proven time and time again that she can deliver high drama to perfection, but what makes it all the more impressive is that she is able to deliver comedy equally as well. As the character of Sally has aged, we have seen her develop traits that even Hyacinth Bucket would find ridiculous.
She is the proud owner of the only conservatory on the street, and whilst she would welcome you to pop over to marvel at it, she would prefer if you didn't consume beer whilst doing so, as that would be, in the mispronounced words of Sally, "uncouthed".
Her regular failed attempts at reaching senior management level are a constant source of amusement and, although we're only a few episodes in, the current storyline surrounding her attempt to stand for the local council looks set to be up there with her best. Even her love life has provided plenty of laughter, with Sally and Tim looking set to be this generation's Jack and Vera (and that's not a title I dish out easily).
It's hard to believe Sally's been in the soap for 30 years now, in part because she's barely aged a day and in part because she's been an unsung hero for so long.
Her versatility and skill have helped to cement Sally as one of Corrie's most iconic characters, and it was great to see her talent finally recognised at last year's British Soap Awards. 'Best Comedy Performance' is a title she should have held years ago, but hopefully this is just the beginning and Sally will continue to light up our screens for many years to come.
