I'd like to think it might be.. vary from one person to another, considering I can't quite find the real pattern but maybe how they carry themselves as an individual? How they speak and their choice of words as well as how they try to connect with me and not just talk to impress but really.. communicate, how they behave, their personalities, and their looks (I won't be a hypocrite to admit that their appearance matters to me), how they treat others around them, their friends.
