It is the truth FS. Take out the mating or sex factor from flirting and you will see how good this is. I admit that I have always flirted and with mostly older women and even the grandmother I meet. Because appreciation and compliments is all that is needed to win a woman's heart. To make them feel good and to just make their day.

And honestly I have done this almost all my life. If I can make someone happy with some subtle flirting I will do it;)
