IOIs are very real , you can easily observe them in the wild and they becone very obvious when you start learning about body language .
But just her twirling her hair is not enough , its just a single body language sign and it could easil just mean that shes nervous and trying to calm herself .
You need to look for multiple IOIs at once to see if shes really into you .
For Example :
Chad is talking to a girl and the girl shows these signs :
- Twirls her hair
- bites her lower Lip
- crosses her legs while standing
- Feet pointing towards him
- Open body language / not protecting her stomach or her neck ( crossing arms for example )
- exposing her neck
- puffs out her chest ( to shows what shes got )
- leans in closer to him ( to smell him / pheromones )
- tilts her head downwards and looks up at him with big eyes ( submissive )
- Touches him ( example - iniates hugs )
- doesnt mind being touched by him
- Smiles and laughs at whatever he says and doesnt fake it , the smile reaches her eyes .
- her Pupils dilate while looking at him / talking to him ( sign of being comfortable )
- she can be caught glancing at his crotch
- when Chad is present in the Room , even if he is at the other End of it , you can observe her looking over to him from time to time unprovoked - she will ignore other males.
- and the list just goes on .
A single IOI is coincidence
