Girls know when their guys are flirting not so much based on the guy’s behavior but more based on the other girl’s behavior. It is entirely possible that the girlfriend used the same exact techniques that this female stranger is using to get her guy in the first place and she can sense another scam a million miles away. Even if the guy was just being a nice guy and having an innocent conversation the girlfriend will automatically swoop and accuse her man of being the 1st flirt in that strange female’s evening. The older a guy gets the more he realizes that not only should he avoid situations like that all together if he really wants to avoid troubles but he should also not even bother to argue as all guys know they just are not going to win that particular argument. So being a nice guy always has its disadvantages when it comes to innocent conversation but being a nice guy is the perfect way for single guys to get flirting.
Women love to laugh and the way a woman says she can tell if a guy is flirting with her is if he tries to make her laugh. Making some girls laugh is very easy and if that is all a guy needs to do to flirt then it is no wonder why so many guys get accused of being teases and flirts. But flirting is so hard to do sometimes because it can be difficult to read what a person is trying to tell you in any given situation. It is so difficult for a guy to tell if a girl is receptive to his flirting, if she is interested in him, and if he should take the flirting to the next level which would subtle physical contact. There is such a violation of space when it comes to the next level of flirting that if you read the signals wrong you could end up with a drink in your face. So just be a nice guy, make her laugh, and see if she makes that first move. If she doesn’t then good luck to you partner!
