Hello @chbartist!
Learning to enjoy and appreciate imperfections will be very interesting for lonely people. But I think it would also be very interesting for both parties to learn to appreciate the differences of the opposite party, the lonely people with those who are not, and the people who do not live in solitude with those who do live that way.
That would greatly expand the perspectives of the whole world, since each one would learn from the other, and would bring us much closer between people. Or at least in the idealistic and moral part, lonely people would be less lonely.
