Happy, you're too young to remember watching the Berlin Wall come down at the end of 1989. East German border guards, whose job had been to kill anyone trying to cross that wall, had also been its prisoners. To cross the wall meant death. Few East Berliners imagined it could ever come down - it was a wall around their lives, and had been for 28 years.
For the demolition, West Berlin had a huge party. People came along to help chip out the bricks, take souvenirs, and generally be amazed that this thing was finally going. On the East German side, it was as though nobody really believed what was happening. The BBC had an amazing long shot of one young soldier, standing on the rubble, looking ... lost. The first Eastern Bloc cars (Trabants, I think,) rolled over the border and their occupants looked, not jubilant, but dazed.
I couldn't find the specific images that stuck in my mind, but I'm posting these for you. Do the border guards look excited? Have they jumped down to join the West Berliners' impromptu bierfest? Nope! They're just standing there, looking awkward, thinking "Eh? What happens now?"
They did jump down, later, and joined the party. You will, too. But cut yourself some slack: your world's changed, you're outside the 'wall', and you're in shock.
