I get paid to like you and I really do. But the people I befriend elsewhere in my real life have various categories of like and it takes a lot of history/mutual interest to transcend the crew/passenger relationship.
(Well, unless you are a guy and you have a functioning penis. In my life on the road, it rapidly became clear that there was an extremely blurred line in those circumstances.)
But for me, I don’t want to invest emotionally in a relationship that I won’t have the time to sustain. I do honestly mean it when I ask people to keep in touch but these relationships invariably fizzle out because they don’t understand why I am not making that much of an effort: the very circumstances (i.e my job) in which we bonded mean that I don’t have the time to put in a 50/50 friendship effort.
But I can’t say to them, “Hey, I want to be your friend but it will be 60/40, 70/30 relationship at the very best.” Very arrogant and, to be honest, I wouldn’t accept a friendship like that, either.
Sometimes I feel sad about missing out on friendships with really great people. We both have to accept it is circumstances, not lack of interest.
Maybe this is why we develop such an intimate relationship with our work partners? Like a Clayton’s marriage. We bond closely with each other because we need to.
