Berliners were shocked when they woke up that morning. What had once been a very fluid border was now rigid. No longer could East Berliners cross the border for operas, plays, soccer games, etc. No longer could the approximately 60,000 commuters head to West Berlin for well-paying jobs. No longer could families, friends, and lovers cross the border to meet their loved ones. Whichever side of the border one went to sleep on during the night of August 12, they were stuck on that side for decades.
