A Complicated Melody

I was at the 14th floor lobby waiting for the elevator on my way to lunch when everything shook. At first I thought I was having a vertigo attack. I leaned to the wall trying to keep my balance. When I saw the door shake intensely and the printers moving, I knew then it was an eathquake. 5 seconds passed and the shaking still did not stop. I rushed to the door hoping to go back to my office and hide under my table. I twisted and pulled the knob but it did not open. It was like playing tug-o-war with the door. Yes, I was in panic. Not my shining moment (*diana grins shyly*).
