Body langage is a really important aspect of social dynamics. You can have a lot of fun with your sets just by observing other people’s body langange inside the venue and talking about what you’re seeing. It’s especially fun if there is a guy and a girl and the guy is in the process of getting blown out. Just pick out a set and insert some interesting observations.
“Wow, look at that guy, he’s totally hitting on her and she is totally not into him. Look at how he is leaning into her and she’s totally leaning away. Isn’t it crazy how so many guys are so clueless when it comes to talking to girls?”
“Oh man, that guy keeps talking and talking and she just isn’t having it, look at how she keeps giving her friend the ‘get me out of here’ eyes.”
“Wow, that guy is totally smooth, look at how he’s leaning back and that girl is leaning right in on him. Doesn’t he look like the mack? Bet you wish your boyfriend was cool like that.”
These are just a few examples, but there are tons of free-form unscripted observations you can make. Practice and play around with them, universal themes will develop. Work on tying them into your own personal DHV stories and experiences. And most of all, have fun!
