Earthquake!

Two, maybe three weeks ago we had a small earthquake. I was in a classroom waiting for my teacher to show up. It consisted of a loud bang and a small tremor in the building. I've never experienced an earthquake and I wasn't expecting one in Beijing, so I thought it was just blasting at one of the 300 nearby construction sites. After class, all of the earthquake first-timers giggled like schoolgirls. Now I'm ready for a real earthquake. I just hope I'm outside.
