You need to keep the conversation going if you want any chance of being attractive to women.
One thing to focus on is to always ask open ended questions, and try to ask about the last thing she said.
Her: Ya, I love vacations. It's been forever, but the last one I went on was a cruise to the Bahamas.
You: Oh man, I love the Bahamas - what was your favorite part about the Bahamas?
Her: I loved the weather of course, but I really enjoyed the local people, they were so open and nice.
You: I agree, I love being around people who are just open to new experiences. (insert question about the most liberating thing she has ever done).
