I was in Berlin when the Wall came down. In fact I had been living there since 1984.
I had just woken up from an early evening nap when one of the people from the Wohngemeinschaft where I was living told me the Wall had come down.
This seemed strange since it looked perfectly intact only an hour before when I had gone to sleep.
Of course my room-mate was exaggerating. In fact, the Wall hadn't come down -- it had simply opened up. That's an important distinction which I'll get back to in a moment but at that point it really didn't matter. I like everyone rushed out to welcome the incoming East Germans at Checkpoint Charlie, buying a bottle of Sekt (German sparkling wine) along the way.
