Huns at the gate

Time for the daily assault. The pounding that is either freeweights being cast aside after a lift, or Huns at the gate with a battering ram, has begun.

I like my explanation better

Every day at about 5:30, the building starts to reverberate with periodic rumblings that sound sort of like thunder. It apparently is a heavy pounding coming from the floor below us. Someone today said it is from the fitness center downstairs. The sound, apparently, is the impact of heavy freeweights being dropped after a lift.

I think there are ways too many "booms" coming to just be freeweights dropping. I am virtually certain that the sound is actually a bunch of Huns using a battering ram to try and break down the door so they can pillage. I could be wrong.
