However, this was not always the case; in 1919, during a trip to Marple Lake, Minnie left Armistead behind to walk, and he turned to Ena Sharples (Violet Carson) to advice.
Concerned, Ena asks Lucille Hewitt (Jennifer Moss), Bet Lynch (Julie Goodyear), Rita Littlewood (Barbara Mullaney) and Norma Ford (Diana Davies) how Minnie has been behaving recently, but gets no solid response.
She first appeared in September 1973 when she was being chatted up by Ray Langton (Neville Buswell) and was eventually caught by Vera drinking in The Rovers Return.
Tricia appeared in Coronation Street again in 1974, when her grandmother Megan Hopkins viewed the Corner Shop with an interest in buying it.
Her friend Gail Potter (Helen Worth) was keen to match-make the pair, and took a polaroid just as Ray kissed Tricia.
Her main priority being to enjoy her youth, Tricia did not concern herself with her family's problems, and bemoaned the fact that despite having her own flat, she was still under their thumb.
When the rest of the family left the Street after a failed attempt to blackmail shop owner Gordon Clegg (Bill Kenwright), Tricia returned to Coronation Street and convinced Gordon to rent the flat to her and Gail, with Blanche Hunt (Maggie Jones) taking over the running of the shop.
In 1975, when a cigarette caused the warehouse to burn down, Tricia was trapped in a toilet and rescued by Ken Barlow (William Roache).
When Elsie Tanner (Pat Phoenix) returned to the Street to manage Sylvia's Separates, Tricia and Gail both asked her for the assistant's job.
In 1973, Vera caught Tricia drinking underage in The Rovers Return, and rowed with landlady Annie Walker for allowing it.
Vera did not stay long though as only a few weeks later she left to take care of her sick mother, only returning when she died a few months later.
Granny Hopkins was interested in buying the shop using Vera's inheritance, but the pair did not get along and when the pair were moving furniture in the corner shop accommodation and found owner Gordon Clegg's (Bill Kenwright) birth certificate, Vera assured Betty Turpin (Betty Driver) that they would not tell anyone that it revealed that she was Gordon's true mother, not Maggie Cooke (Irene Sutcliffe).
Vera knew that Granny could not be trusted, and tried to rein her in as she used the information to try to secure a lower price on the shop from seller Gordon.
Vera and Idris excluded her from the acquisition of the shop, keen to make peace with the Cleggs, but Granny sent Gordon a letter telling him the truth anyway, causing him to change his mind about the sale.
Since leaving Weatherfield aged fifteen in 1964, Trevor had worked his way into the building trade and cut virtually all ties with his northern roots; when he married Polly in 1971, he told her his parents were dead, although he did write a letter to Stan (Bernard Youens) and Hilda (Jean Alexander) that year before marrying, which he thought they'd ignored as he never received the reply they sent.
When Trevor arrived home, he was not happy to see his parents but he was polite with them, although he was visibly embarrassed at the reminder of the working class community he'd abandoned.
Polly admitted that she did not like them much either but that she wanted to invite them to stay the night as it was getting late, but Trevor was against this and rushed them out of the house before their dinner guests arrived.
