Summarize:

Nod, make eye contact, and stay focused on what a girl is talking to you about. Try to understand her emotions and point of view. Imagine how she feels as she speaks, and react accordingly. Teen boys who empathize with their female peers are more likely to have girlfriends. For example, if she's upset, hear her out. Then try saying, "I'm sorry that happened to you." Think of ways you can connect with each other. Make conversation about school or hobbies. Try asking her questions about herself, which will show you're interested in what she thinks. Teen relationships often start with friendship. If you've spoken to her before, try asking if you can add her as a friend on a social networking site. If you've never spoken to her before, try asking her about a class, mutual friend, or after-school activity. Try asking, "What type of music do you like?" Notice something about a girl that you can give her a positive comment on. Don't make something up; put thought into noticing something she's put effort into. Then offer a sincere, heartfelt compliment. Try saying, "Your hair looks great today." If you've witnessed her playing a sport or creating art in a class, you can compliment her on that. Make kind gestures whenever possible. Open doors for people. Offer your help when it may be appreciated, whether it's with carrying something or studying. For example, offer to help a girl with putting her coat on. If you see a girl carrying something bulky, try saying, "I can carry that for you." If you see a girl struggling with a school subject you understand, help explain it to them or offer to study together.
Be a good listener. Make friends with girls. Give girls compliments. Practice good manners.
