Who kicked my bed?

I am dozing off to sleep and suddenly the bed shakes and I pop up alert. An earthquake shook me awake. I got up to check on my son and he asks, “what was that?” I fire up the computer to check the USGS site and here comes another. Two 3.9 quakes only 5 minutes apart. It has been a couple of years since we have had any that strong here.
