Quake – a swaying

After a night out, the last words I told my Japanese friends was ; well I have been here three weeks and not a quake near me. Then again havent been around here in Tokyo much either. Tomorrow I leave for the mountains again so I guess no shakes for me this time in Japan.
Then sure enough, I just got back in my hotel room when a long but not disturbingly strong sway back and forth started. Mind you, I don’t drink alcohol, so even after a night out, I identified it as a quake LOL
