Though it might not strike you as much of a skill when you're shooting the bull with friends, holding a conversation with a woman -- in whom you're interested and whom you don't know well -- is a skill, and one that takes some practice. Listening and actually paying attention becomes infinitely more important when talking to someone you are interested in. You want to come across as both confident and empathetic, which is something of a balancing act. Laughing at the wrong moment can make you seem like a psychopath and agreeing to the wrong statement can make you seem like an uncaring jerk. Keep your ears open. Ultimately, being able to explain and adequately express yourself is the smoothest skill around.
