What did the swallow notice while flying over the city?

The swallow was flying over the large city when it saw the wealthy having fun in their lavish homes, the beggars waiting at the gates, the white faces of starving children staring listlessly out at the night streets in the dark alleys, and two young boys trying to stay warm under the archway by lying in each other's arms. They fled into the rain when he spotted the watchman yelling at them.
