Men are easily flattered by a woman’s attention and the best way to show that is by showing your interest in everything he says. This is not really hard to do since you will be naturally drawn into his words if you like him. I am not sure why, but it seems that men like to quiz women about different things even the first time that they meet so be prepared to answer a parade of questions about your work, your ex, your family, and everything else. And learn to reply intelligently if you want to develop an even stronger connection with him.
