　　Last night, my colleague invited me to dinner. When I got to the appointed box, I found that I had gone to seven or eight people, and I basically didn't know them. Colleagues came over to explain to me in a low voice that they are all her friends. Considering that everyone is usually very busy, today is just the weekend, so we invited them together. When I was eating, I was next to a middle-aged woman, about 40 years old, dressed in fashion and with exquisite makeup. She took the initiative to ask me about my relationship with my colleagues. I said it was a colleague relationship, but we usually get along. She smiled and asked me if I had a girlfriend. I said I was married. She gave a meaningful smile and then stopped talking. After what she said, it's impossible to give me back. Don't know what to say. After a while, she took the initiative to add my WeChat. I wanted to refuse, but she was very enthusiastic, so I didn't have the nerve to refuse. I originally planned that even if I added friends, I wouldn't contact each other in the future, just meeting by chance. Who knows that after returning home from the party, she kept sending me voice messages, saying that she wanted to have dinner with me alone, and she would like to ask for advice when the time comes. Let's help me analyze it. What is the high probability? It won't be borrowing money, will it? Friends of colleagues, is it okay if I delete them?
