Ooowy!

All parents will be familiar with this one.  You are standing in another room.  You hear a crash.  Silence.  You wait for it.  The sound starts.  It begins low, like an ambulance in the distance.  It builds into a wail.  "Mama, Daddy!".  The pitter patter of little feet running towards you.  They show you where they hurt themselves.  They ask you to kiss it.  You do and, magically, they feel better.  "Are you ok now?"  "Yes".  And off they go.
