Communication Narrative

• A man walks up to a park bench and sits down next
  to a big lady wearing a red dress. She is reading
  a newspaper and drinking coffee. Also on the
  bench is an older man wearing a plaid shirt and
  holding a cane. Coming down the road in front of
  them is an old bus that is trailing white smoke.
  The bus jams on its brakes to avoid hitting a
  white cocker spaniel, causing several cars behind
  it to bump into each other. The drivers in the
  cars get out and exchange insurance information
  and a police car arrives.
