When responding to the question, "Why do you want to talk to me?" it's essential to be genuine, respectful, and honest. Here's a straightforward and respectful way to answer:
"I wanted to talk to you because I find you interesting and would like to get to know you better. I think you have a great personality (or any specific qualities you admire about her) and talking to you seemed like a nice opportunity to have a meaningful conversation."
Remember, sincerity and honesty are crucial in any interaction. It's okay to express your interest in getting to know her better, but also be prepared for her response, whether it's positive or indicates that she's not interested in further conversation. Respect her feelings and boundaries, and if she's not interested, accept it gracefully and move on. Everyone has different preferences, and it's essential to be respectful of that.
