1. If you are friends or trying to establish a relationship:
You can express your understanding of her hobbies, and you can also share some of your own views or experiences on dolls. This will allow you to have more common topics, and also help to enhance mutual understanding. For example, you can say, "I had a doll that I liked very much when I was a child. She is my best friend. What do you think is special about your doll? "
2. If you are lovers or are building a relationship:
You can take this opportunity to learn more about her inner world and ask her why she likes dolls, and if there are any special stories or emotional connections. For example, you can say, "I'm glad you like dolls." Can you tell me why you like them? Did they bring you any special memories or feelings? "
3. If it is an ordinary friend or working relationship:
You can respond to her preferences and express your gratitude for sharing this information. For example, you can say, "The doll is so cute! Thank you for telling me this information. I'm glad you like it. "
In any case, the most important thing is to respect her hobbies and show sincere concern. This will not only bring your relationship closer, but also help to enhance mutual trust and understanding.
