When flirting, you should be on the lookout for signs of interest. If you see at least four of the following signs in the body language of the person you are with, it is likely that they are interested in you, and you are being given a green light to move things further!
1. Lengthy eye contact. eye contact maintained over a period of four seconds or more is unusual between casual acquaintances or friends, but not amongst lovers; and it can be rather intimidating, but if you are flirting with someone and they know that you could be flirting with them, they are sending you an explicit message with the power of eye contact!
2. Mirroring. If your posture tends to be similar to that of the other person and tend to do what you do at about the same time that you do it, they are either consciously or unconsciously developing a rapport with you.
If the person wishes they were somewhere else, they will likely have turned away from you, even if they are facing you; look for the legs and feet pointing somewhere else, perhaps even towards a door. Note that this only applies where you are in a one-on-one situation, and doesn`t apply between groups of people.
Conversely, somebody leaning away from you, perhaps with their arms and legs crossed, is displaying a lack of interest. If they are leaning in towards you and you do the same, you can be sure that something more is likely to happen, because it is very likely to lead to the next stage!
5. Touch. Firstly, if you are close enough to touch easily then that`s a good sign. There are several things to look for. Hands resting across a table, on your side of it, that are close enough to touch, typically from a woman, signify interest; she doesn`t want to touch first, but she would like to be touched!
Picking off a piece of lint from clothes, whether it exists or not, is another good sign. Touching upper arms when sitting next to each other where it is not especially crowded is often done. Lingering touches send an even stronger flirting signal!
6. Raising eyebrows upon first meeting. This is usually over very quickly, lasting about a quarter of a second. As it happens on first meeting, you need to be quick to look for this one! the longer it lasts, the more interest lies beneath, as it can last for up to a second.
