The fall of the Berlin Wall made many people feel that dreaming was possible. A man from East Berlin who had just turned eighteen said, " I had started enjoying my own life---(dot,ellipsis). Suddendly, the wall dropped and the world was open." That fredoom led to this man meeting his future wife--(dash) an American. Yesterday, both of them released one of the 8,000 white balloons that wove/weaved through Berlin  along the path of the former wall.
