Small stories from a big world

A few months ago, on a Saturday, the sound of a tractor or excavator woke me up early. That typical growl of a heavy engine, deeper and louder when the machine is doing heavy work.

Yes, supposedly, because I have not yet seen the Sophia robot in action. It is always parked neatly by a wall or in a corner, charging. Anyway, everything
