Our lonliness

Who has not, at some time,been lonely in the midst of a social event?
The feeling of our separation from the rest of life is most acute when we are surrounded
by it in noise and talk.
We realize then much more than in moments of solitude how strange we are to each other, how estranged life is from life..
the wall of distance, in time and space, have been removed by technical progress; but the walls of estrangement between
heart and heart have been incredibly strengthened.
