Every once in a while (bi-weekly or so) we have a mini-earthquake in our apartment. Everything rumbles and shakes for a couple of seconds and then it's done. The first time I thought it was a fluke. Maybe even the second time.
Now I'm pretty sure that the quarry or mine or whatever you call it that's not too far from our apartment is the source of the mini-quakes. Maybe they're blasting stuff.
Well anyhow, I never wanted my life to be too stable.
