  Most of what falls out of my keyboard is dust and ashes.
  I live downtown (or what used to be a "downtown") and I can dust one day
and everything is clean and shiny, then a couple of days later is covered in
dust again.  
  Reminds me of the joke of the little girl who was taught in Sunday School
that we come from dust and return to dust.  Helping her mother clean one day
she sees dust under the bed and wonders if someone is coming or going.
