Think of a few of your favourite things...you've just
created some boundaries.
We create boundaries all the time without being aware
of it. Whenever you distinguish things or activities (systems)
from each other, or from their environments,
usually by putting a name to them, you're creating boundaries.
Talking, listening, organising a meeting, doing the washing
up, Africa, Europe, a wheat field, Forest Common, a town
in the countryside, sad and happy emotions. All of these
things have boundaries defined by people (who else gives
names to things?!).
