If you meet someone, you have something in common with them already. You're in the same situation as them. Also, think about things that happen on a national or statewide scale. Talking about pop culture is a way to carry a conversation with someone you dont know. Most people will reveal information about themselves as you talk to them, and you can ask them about it later. Also, the best advice I ever got was that everyone want to meet new people, who bring new things into their lives.
