i thought you were coming out of the closet as well and got excited
anyway, i don't believe anyone truly interacts with every individual the same way. that being said, i also believe that we assume different surface roles in social situations as a way of getting by with perhaps the least resistance in some circumstances (e.g. as a customer, student, caregiver, work roles etc.). most of these circumstances are not fit for genuine interaction, although in many cases they can be a way toward developing one.
for instance, we may take on politeness as a way of first relating to someone, even if we don't particularly like them at first or agree with them. although politeness is done mainly as social ritual and is quite surface in its execution, it's really important in establishing mutual respect and a root to which deeper bonds of friendship or love can form. another example would be that sometimes we may find ourselves as social chameleons who mirror the other person. yes, we when look at ourselves doing this we may feel somewhat fake and displaced, but i think it does found a mutually friendly atmosphere, thus serving more purpose than just completing the interaction as smoothly as possible.
politeness and a 'friendly act' can pave the way, but developing beyond social roles requires more reflection and awareness. i think you need to first, of course, be interested in deepening the relationship. also, it may be necessarily to let down your guard so as to have faith that the other person should have the capacity to see you as is. social roles tend to emboss us as well-oiled machines who strive for smooth perfection. letting down the guard then, also can mean showing humility, speaking honestly (but not harshly), and allowing yourself to make mistakes or reveal them. i find that casual quips, a laidback demeanor, and recognition/acceptance of one another's blunders actually brings me closer to others. it makes us more human/real to one another.
we may find that maybe very few people are open or aware enough to genuinely relate to us without putting on a external face or keeping a guard on how they relate. many times, we ourselves are not aware enough to take down our guard and see that we too are acting a role. we may find ourselves reverting back to old habitual ways that have become readily ingrained like a second nature when it is genuine interaction we actually want. sometimes, it just takes time (time to familiarize, feel safe/comfortable, etc.). other times certain people may not be the best person for us to develop a relationship with.
