While working ( i'm a shop assisent ) comes in the shop a family, turists. I started talking about the products to the couple and their daughter was looking at me all the time. As I made eye contact with her she will look down and this happened a couple of times. But when they were leaving she was looking me throught the window and we made eye contact for a few sec. then something passed thru my mind and i looked away... this happened twice because they stopped also in front of the window.
What effect does looking away make? Another time should i look at her until she looks away?

Look at her mouth and at the same time look at her left eye with your left eye and hold her gaze. I'll amost guarantee you that if she likes you she'll give you a "turned on" look.

thank you for the advice
next time i will try it :*

don't stare all day, just go talk to them

looking away, and not breaking EC really doesn't make very much of a difference, holding the eye contact demonstrates confidence and telegraphs interest to the girl, and you can also see if she is nervous and showing some form of submission (preening, smiling, looking down, etc.) the signs that she is nervous are just go ahead signals, but they are totally not nessicary don't overthink this shit, you don't need and approach invite to approach, and simply staring at a girl without approaching won't get you laid, and prolonged staring with no approaching might make her think you are weird

if a girl makes an effort to make eye contact at all, that is good enough, she is looking at you, either looking cause she thinks your hot, or she thinks you look retarded, only way to find out is to go talk to her and test compliance

Instead of looking away just smile, if she smiles back then thats a strong IOI.
Supposedly there is a code to how a girl looks away after eye contact; I don't think it's super accurate but as a guidline it will keep you on the right track.

If a girl looks away upwards: Probably no joy.
If she looks away to the side: She's making up her mind, if she looks back-good
If she looks away downwards: She's identified you as an alpha and it's looking good.

I really hadn't got the time to approach her cause i was working
BTW what's the difference in the approach between daygame and nightgame?
