Sally wants a new bicycle , but her mother and father will not buy her one

because they believe she already has a bike that is in good condition and doesn't need a new one. Sally can try saving up her own money and buying the bike herself or perhaps she could ask for the bike as a birthday or holiday gift. Alternatively, she could try finding a second-hand bike that fits within her budget. There are many ways for Sally to potentially acquire a new bike without her parents purchasing one for her.
