4) Comfort Building correct answer = d
Don't forget it is extremely unnatural to approach a complete stranger. Clearly the girl's guard is up because they have no idea who you are or what you are selling! A good salesman does not scream in your ear "50% off while stocks last!", no, they do it seductively. You are no different. Generally you will make a girl uncomfortable if you telegraph interest right away. Putting them at complete ease is key. Talk about an item in a shop window perhaps, show them you are not needy, but confident and fun. Don't forget, no matter how beautiful a woman is, there is always an ex-boyfriend out there with not a good word to say about her. So know that there may be a good reason for that. Therefore, you cannot decide you are attracted to a girl before they have qualified themselves to YOU! Take it easy, build rapport and then take it further if you want to.
