Even something as simple as the way you compliment someone or thank them for something. Anyone can see "Cheers, thanks" or "Your jacket looks nice" and not really put any effort into the comment or say it without any meaning.

Guess it comes back to the whole "Its not what you say its how you say it" - show genuine sincerity & compassion/emotion. Obviously when it comes to women you won't want to get carried away with that - but for example out with friends on Saturday I took the time to tell a friend I liked the way she'd done her hair (she is pretty hot and popular with guys) and her face went bright red and she was so pleased.

If I can figure out how to do that in a more seductive/confident/manly way I think I'm onto a winner.
