excellent.
just a quote ( I have similar pupils here, but unprogrammed ...)
A very distinctive aftermath of the fall of the Iron Curtain was the several
thousand border guard dogs that became unnecessary. In Berlin, most of these
dogs were adopted by Westerners. Marcus reports that whenever the new
Western masters took their dogs on walks near the former Berlin Wall, "the
dogs suddenly were deaf to every call and ran their programmed beat without
veering right or left. The wall itself has disappeared so completely that
even native Berliners can't always say exactly where it used to stand. Only
the Wall-dogs move as if tethered to an unseen leash, with absolute
certainty, following the old border along its zigzags through the city"
(Marcus 1995: 23-24). The Wall exists still! These dogs continue the story
most people no longer want to hear. They insist on the reality of a history
that is no longer real for most people. Ironically, it took dogs to remind
us of our history, whether unpleasant or pleasant, from which we can not and
should not escape! Or we will repeat the mistakes of the past (of both the
West and East, in this case) and wonder why we are once again experiencing
what we should have learned to avoid.
they act like dogs for the blinds. wich sense do they use ? just plain
memory?
they know their way until they die.
we humans just forget too many things. even alive.
