After first appearance, it will come to talking. Why not begin your talk with something to appreciate your date. Let him/her feel good about him/her with your very first sentence. Again it should not be a lie, but a genuine compliment. Anything about the other's looks, dress, style, skin or whatever that you feel can be genuinely appreciated. Do that and see a smile breaking on your date's face. After that, keep quiet and let him/her converse. Let him/her talk about whatever he/she wants. Give the center stage to your date. Listen attentively and respond in between the talk to convey that you are intently listening. Don’t turn your eyes away from your date's face while they are talking. Keep an eye-to-eye contact with a smile on your face.
