Loneliness is not a required part of privacy any more than privacy or seclusion are required for loneliness to be present.
I’ve been my most lonely in large crowd-filled noisy rooms, talking as much as anyone. Alone or accompanied, that loneliness experience is about feeling, not about place.
Privacy isn’t a place either, but it feels more isolating. Privacy can be ‘any place’ yet so often it feels elusive, impossible to find anywhere.
But loneliness is not privacy. Privacy is not loneliness. Intellectually we know these are separate things, not required in the same place at the same time – but we assume, there is a connection.
Sorting one from the other doesn’t make either easier to understand. I understand loneliness best when I’m not. And I understand privacy best when I don’t have it at all.
