4.7 is definitely a good rattle. Nothing to be ashamed about. Once you get over 5.0, you really start to worry because thats when things start to break. My biggest was 6.8 and that resulted in smashed dishes, loss of power and water for a week, and the roof shaking off the walls.
There are two kinds of quakes--I forget the exact terms, but one is a rolling type of quake and the other shakes up and down. Rolling quakes just kind of jiggle you, whereas the up-and-down quakes shake you the fuck up.
I have the US Geological Service site bookmarked because I'm always curious how big they are when I feel them. Check out your details:

By the way, I got the hangover I measure all hangovers by in York.
