To add to all the earthquakes happening around the world right now, we had a 3.9 one on Thursday afternoon. Our neighbor had just shut his door so the whole house shook, and less than 2 seconds later, the house shook a different way! It was pretty fast. I watched one of my plants shake rather violently for a bit!
I tweeted about the quake and one of my online acquaintances was like "Seriously? You had an earthquake? Are you okay?" Which is not an abnormal response. But, then he talked to me on skype later and asked "Did you really have an earthquake?!"
Yes! How hard is that to understand! We have several a day. You have thunder and lightning, we have earthquakes! Poor analogy, I know, but it's just so common here.
