I was at In-N-Out tonight and I decided to open a two set. I used a "is it cheating opener" about my friend who thinks he needs to break up with his girlfriend because he saw a picture of her making out with another girl at a party. One guy said "yes" the other guy said "no". The opener worked great. They both put down their cell phones and were engaged. We chatted for a minute. The problem is that I didn't have thing for after the opener.
Any suggestions on how to transition from an opener to a topic that I can continue with.
