I've been studying and implementing the standard TRP procedures for improving my social game. Lifting, eating right, body language, posture, power talk, etc.

I've seen it improve my social value in all the circles I am involved in, as well as improve my own self-evaluation. I could not be more grateful for discovering this means of improving my life.

However, there is one area where I find myself consistently having trouble and that is detecting Indicators of Interest.

Beyond the blatant IOIs such as increased physical content, or explicit invitations ("I think you are sexy", "I like your hair", "You have nice arms", etc.) I often find myself only realizing I was given an IOI after I've replayed an encounter in my mind hours or days down the road.

As an example, I a regularly visit a local corner store for the occasional necessities of an out-and-about single guy's life. There are quite a few 6's, 7's, and an 8 who work as clerks at this store and I find myself failing to detect indicators until I've left the store. Just yesterday, I visited to pick up some things and the store was not very busy.

As soon as I walked in, all 3 of the girls who are working in the front of the store snapped their attention to me and sang in a chorus of "Welcome to Cornerstore!" which is not unusual.

However, upon replaying it in my head, I realized that 2 of the 3 had put a lot of mustard on their greeting, and 1 of these 3 who was checking me out a few minutes later was doing everything she could to keep me engaged in conversation.

I was totally clueless. I made small talk with her like I would any other friendly stranger and then went on my way.

What can I do to improve my detection and ability to react accordingly? Is this something I will just have to gain proverbial battle experience in order to improve in?
