I find myself in situations where I'm late for school or work and I see some cute girl walking by but I don't have time to approach and get to know her...I've heard something RSD Todd talked about which is the 30 second number close but I don't remember how it goes...Does anyone here remember it or knows something similar??
Second question is I also find myself in situations at university where some hot girls either leave early or arrive very late...I don't have time to run game properly, my only bet is that I sit next to them and do rapid game...How do I number close in that situation inside a university class without being "the pickup guy" or making her feel slutty in front of people? Does it need to be indirect? Like "I'll send you this or that, let's keep in contact"?

Before anyone says it, yes I do actually meet other girls in situations where I have enough time...I do day game and night game and online game. I just wanna get more reference experiences.

Thank you in advance, you guys rock
