What makes an action, flirting? How do you differentiate it from thinking someone is just being nice or friendly? Has it happened to you to be naturally friendly and misconstrued as flirting? Or have you misjudged another? Does the labeling depend on the intentions of the person doing the act? For exmaple, if it's not his intention to flirt (or not even aware) then it's not flirting. How much does the perception of the receiver or those that can observe the act, weigh in making a call that there's flirtation going on? Say, someone said it's not his intention to flirt (and he's telling the truth) but to everyone else it's obvious he is flirting. Does that make his actions, flirtation?
