If my co-worker hadn't said something, I might not have noticed it at all. When I did, it was a most pleasant rolling. I guess my negative reaction to the reaction is because she nearly panicked - and so when twitter and facebook naturally exploded with something actually happening, it seemed a bit overmuch. Anyway, my co-worker kept insisting it was a huge quake, and the sensation must have been dampened because we we feeling it from atop a tall building.

Northridge was scary. Everything since has been quite fun.
