This has happened to me more than once and I almost don't believe it when my friend told me this.
Me and a good friend of mine usually hang out every few weeks or so and just go cruising around our city and just go into whatever places strike us whether its guitar center, pawn shops, perhaps more importantly the mall.
Anyway we were heading back from just chilling out the other day and I had been peacocked (because hey, isn't everybody peacocked at the mall?

) and my friend just casually mentions "Man I couldn't believe how many women I saw checking you out today!" and I just had a dumbfounded look on my face because I hadn't made eye contact with any girl all day (that I could remember except for this one 50 yr old woman on her smoke break who started hitting on me).
I just asked him if he was joking and how he saw all of them and he said that when he used to be a bouncer he would always be watching people interact at the bar and in the club when he wasn't busting people and so he could pretty easily recognize all the signals and IOI's. (btw I recently introduced him to the Game)
I know a lot of this is still inner game type stuff and that I should be taking full advantage of these blatant AI's (Approach Invitations). I have a good self image and believe that I am reasonably attractive physically and we obviously all have better traits that we want to share with the world and with women, but for some reason I can't recognize my own potential as a proficient pua especially as a "natural".
Does anyone else have this issue?
