I was thinking how amazing it was that the world contained so many lives. Out in these streets people were embroiled in a thousand different matters, money problems, love problems, school problems.

And in some houses people were getting old and sick and were dying, leaving others to grieve. It was happening all the time, unnoticed, and it was the thing that really mattered.
