If you move away when someone casually touches you, you'll be sending a sign that the flirting behavior is unwelcome.
Actions that you think might just be friendly gestures can actually indicate romantic interest.
One of the hardest flirting signals to detect is eye contact.
If the shy smile was a gesture of embarrassment for getting caught looking at you, the person will look away again.
If the intent was shy flirting, however, it's likely that he or she will maintain eye contact and smile even more this time.
There is a big difference between a polite smile and one that is truly open.
When a person's smile reaches the eyes, and the whole face seems to light up, that's a sign of genuine affection.It can sometimes be difficult to distinguish casual eye contact from flirting.To tell the difference, you have to know what separates conversational eye contact from the type that indicates interest.You shouldn't assume that everyone who smiles at you is flirting with you.However, you can tell a lot about a person's intentions toward you and interest in you from the manner in which he or she smiles when interacting with you.If you respond in like fashion by initiating casual contact of your own, your behavior lets the person know that you recognize and reciprocate the potential interest and may be interested in getting to know him better. When someone makes an effort to make you smile or laugh, they're often trying to impress you with their sense of humor. Giving you a hard time is sometimes a way of flirting.
