Final answer:
The provided excerpts do not mention a character named Mietje, hence the question about why Mietje asks Corrie for help cannot be addressed with the given context. The texts touch on themes of needing assistance and support, but do not relate directly to the original query.
Step-by-step explanation:
The question seems to be inquiring why a character named Mietje asks Corrie for help, but the provided context does not mention a character named Mietje. Instead, the excerpts appear to come from various works of literature, none of which feature a character named Mietje interacting with Corrie. It looks like there might be a confusion with the characters, as none of the provided texts directly answer the original query. The assistance requested in the excerpts ranges from help deciding on a fancy-dress ball outfit to emotional and household support in a technologically advanced home. Each instance illustrates characters reaching out for aid due to feelings of inadequacy, necessity, or companionship.
