What would cause my spoke nuts to unscrew?

So I've got this temporary bike I'm using while the frame of my main bike is being replaced.
However, I got home today, bit of a wobble on the back wheel, and one of the spoke nuts had unscrewed itself right up into the wheel, this happened last week too (and the shop kindly fixed it).
Now I'm pretty sure I didn't see somebody with a spoke key chasing me down and sneakily knocking in a couple of turns whilst I waited at the lights, so what would cause that?

Whole wheel will be sloppy - the slack created by the extension of the spokes the bike "hangs" from allows the tension in the spokes under the hub to release so that the spoke NIPPLES are (too) loose in the rim, and gadually unscrew.
If the wheel was correctly tensioned, the spokes above the hub (from which the weight of the bike "hangs") are tensioned enough to hold tension in the spokes below and the nipples are held in place.
