After the metaphorical parting of the Iron Curtain, the very literal Wall was torn down, slabs were distributed to all corners of the world as monuments to this overcoming. It is a scary proposition to think that these pieces, in Berlin and here transplated to Wiesbaden, New York City and beyond could be recalled, cued to re-assemble like some polarising Voltron on some auspicious date.
Provided that nothing's, no sacrifice, forgot, however, I do not worry that there is a great deal to fear in looking forward.
