When your world suddenly shrinks

Sheep shorn, they are moved into the orchard to graze down the long grass. The llama isn't allowed in as he can kill a fruit tree at twenty paces; not by spitting but by mercilessly peeling off the bark with his buck teeth. So he gets left in the field that now needs topping to remove the sharp tall growth unfit for haymaking, and that can cut the soft part between the toes of the sheep as they walk through it.
The tractor goes round and round as Humphrey mews in distrust. He sits right in the centre, watching his patch of long, semi-camouflaging grasses get smaller and smaller. He decides that the tractor is boss and then swiftly stands and steps sideways into the topped area, peering over the gate to check all his ovine friends are close by. Satisfied, he starts to nibble the cut stems.
