Summarize the following:
If the girl you’ve started chatting with is a stranger to you (or someone that you barely know), it’s important to find topics that you and her both have in common. For example, maybe you both go to the same school, live in the same neighborhood, or both study the same subject. Finding these commonalities will make further conversation more interesting. For example, ask:  “What part of the state did you grow up in?” “What’s your major in college?” Pay attention during your conversation, and note which types of topics the girl seems to enjoy most, or which she expresses an interest in. Then, bring these up again later to continue the conversation and learn more about the girl.  For example, if you know that she likes art, you could deliberately steer the conversation towards famous painters. Or, if the girl mentions an interest in soccer, bring up your own favorite soccer players or teams. The girl you’re speaking to will not enjoy the conversation if her only answers to your questions are “yes” or “no,” as these answers can quickly become repetitive or boring.  Instead, come up with some questions that ask her about her past or make her think, and that will result in a longer, more complex answer. Try asking something like:  “What movie or book character are you most like?” “What are some of your irrational pet peeves?” “What is an unusual fear or phobia that you have?” If you’re in the early stages of chatting with a girl and looking for ways to continue the chat, do not bring up topics that could lead to serious disagreement. Don’t make the girl uncomfortable with probing questions about her exes or past relationships, and also avoid sharing strong opinions on politics. Of course, if you and this girl end up getting to know one another better, these types of topics can lead to important and serious conversation.

Summary:
Find some common ground. Discuss topics that she likes. Ask questions that require more than a yes or no answer. Avoid controversial or sensitive topics.
