Almost anybody can be my friend. As long as they are friendly.
I have almost no friends.
In fact, it is my very friendliness that ensures that this is so.
It scares people off.
I often see people 'acting friendly', but if they are to continue in this acting-out of friendship, it is required of those to whom this acting-out is directed, that they vocally display the 'right' attitudes. Usually political ones. In fact, a visible and vocal display of 'nice-ness' is required, in order to win this 'friendship' which is actually nothing to do with what it purports to be.
Animals, birds, trees, even insects, along with my wife, like me and befriend me, and I them.
They are able to detect my friendship, whereas the vast majority of - almost all - people, are not.
