I probably would. I haven't really gotten down opening sets yet... Namely because I don't do it often.
The only group openers I know are, "Hey I saw you guys doing ____, and I just had to say ____." and, "Hey you guys, I think your friends really cute, mind if I talk to her for a second?". I guess there's always an opinion opener, though...
I usually make my things up on the spot. Today I opened like... a 20-28 year old (I'm 15) and I opened by humming a Backstreet Boys song that was on the TV at my dad's work. She worked there, and she actually started flirting back up until she qualified me - I didn't do it right... But I was doing pretty well until then. We talked music, and stuff until it went a little silent and she qualified me by asking how old I was. After that it was game over. Lmao, asked how old I was and what grade. I think she got suspicious right after I told her I didn't have my license
When I told her how old I was my dad walked in and saved her. She just walked away. I might've been able to save myself... But I just let it go.
Another opener I used today was speechless. I just gave a girl a certain look - then she opened me. She said, "Hi..." meekly.
I'm a strong believer in natural and inner game, but I also think that technical over-tones and structure can boost your game because you can name where you are in the interaction, and know where you can take it, and how. I usually just used canned materials if I'm stuck... Or I need to be spur of the moment, and I can't think properly - so I have something rubber-banded to my tongue. My default opener is, "Are you single?" or some variation.
Warm regards,
