Well, it depends. If it fits the character or scene and helps convey the intended emotion or action, then it could work. But make sure it doesn't seem out of place or overly odd for the style of your novel.
Definitely not. It violates basic moral and ethical standards. We should uphold respect for others, especially in the context of educational professionals. There's no place for this kind of vulgar and untrue statement in a civilized society.
I'm not your daughter. It's possible you are thinking of someone specific in your life who might be your daughter. But I'm an individual separate from that relationship. We can share stories or experiences, but not in the context of a family relation like that.
I'm not your daughter. I can understand that you might be feeling a bit confused or perhaps there's a story behind this question. But from my side, I have no such family relation with you. We can still have a friendly talk though.
Most likely not. Stories with such titles are often imaginative works crafted by authors rather than being based on real events. But sometimes, they might draw inspiration from real-life situations and emotions.
I don't know for sure. It might be a true story, or it could just be a made-up tale to capture the readers' attention. We'd need more details to know for certain.
Well, first of all, it's important to ensure your daughter's safety. If this friend has some serious psychological problems, they could potentially harm your daughter either physically or emotionally. Maybe your daughter is trying to be a good friend and help, but she also needs to know her limits. It could be that the 'psycho' behavior is a result of some trauma or an undiagnosed mental disorder in that friend. Your daughter might need some guidance on how to handle the situation, like when to step back and seek help from an adult or a professional.
