What I mean is, does everyone have there heart "wired" in a unique way, so that what their emotional needs may be different than those of other people? For example, is it normal for a person to feel that they would feel most happy with a person that they have known their whole life because it gives them a sense of security and familiarity that they feel they can't get with someone that they haven't known very long (they may also hold the memories of growing up with that person very close to their heart), or is that person just experiencing social anxieties that make it feel that way?
