The drop of water.

[hannah]

It's the drop of water that makes the jug overflow is a much nicer way to describe the breaking point. It makes more sense, too - a straw breaking a camel's back works as a turn of phrase, but it's much easier to imagine how just one more drop of water will fracture the delicate surface tension and make the whole thing spill over.

Now, if anyone's got any advice or links on how to get a moodtheme installed on Dreamwidth, I'd be happy to know.
