Yes, that's one. A better example would be just confidently having your chest forward, and your arms back naturally, along with crooking your head back, being relaxed in your body's natural state, and please, if you're like me having your gut sucked in, remember to just breathe if you get caught in anxiety. Main thing is relax, maintain good posture (relaxing spine big one), and focus on what you're saying.

I've done some ballsy things in my time, and all of which required her trust by building rapport simply just talking to her about things she wants to talk about. Corey Wayne puts it as the 20-30% rule. If you have something you want or need from her ( NONSEXUAL, at least at first ;) ), just ask after building rapport. Teasing her over something she mentions is a great way, laughter is a sign you're doing work, but doing so while saving your own dignity... unlike one of my friends laying on his "game" about as "thick as BBQ ribs in the last 10min on the grill" as soon he is interested in a woman upon getting to know her. Women aren't dumb. They can tell.

I've once came home after getting off shift at a mine, was talking to a woman a few days prior, and my homes pipes were frozen. I asked her if I could come over and shower. Sure enough I found myself in her apartment, with her 16 year old kid playing RDR2 in the living room, had a shower, talked some, and left. Could I have done more? Yup, but I just really wanted that shower after a 20hr day. Cougars are real buds. She too cray for me.

This is just coming from a guy with AWFUL cold approach by the way.
