Search Results: grabs your attention

A. You see a guy eye-ing you up. The eye contact is intense and it's obvious he's interested. From afar he throws a line at you. He approaches you like he's Mr Big Shot and he is able to keep a conversation with you going. But he hardly says anything genuine (he does compliment you but you are wondering whether he means it) but he has bags of confidence, which you love, and if he continues speaking he will become arrogant.

B. You see a guy who keeps looking over at you but he can't hold eye contact. He just keeps glancing over. As he walks closer and closer to you you think he is going to approach. He gets even closer and ''half-smiles'' at you. He only half-smiles at you because he is too shy to approach you and is afraid you may not return the smile. He then pays you a genuine compliment and continues walking past you.

Which one of these would grab your attention more, in either a good way or bad way?
