Not sure what to do

So we are standing in the kitchen and all of a sudden we hear a "bing bong bing" come across an intercom in our new apartment, or flat as many of the other teachers call it.  The attention tone is followed by an announcement of some sort, all in Korean.  It goes on for about 60 seconds and Kelly and I say to each other, "I'll bet it's in English next".  We were wrong.  Nothing further from the intercom.  Do we worry?????  We will see. (Hopefully it wasn't an evacuation notice for an approaching tsunami. ;-)
