On ending a relationship --

Let's take a closer look at the flashcube (some of you may remember them from childhood photo shoots, lovingly hinged to the top of a parent's camera). They contain fine wires made of magnesium metal, and when a current is passed through the wires - in the oxygen laden chamber of the cube - a flash occurs. The floor of the chamber is now covered in a powdery substance known as magnesium oxide, its properties quite different from those of the original materials, and the flashcube won't flash again.

My contents are changed.

My flashcube is spent.

Where do I begin? Just took a quick browse through your blog, and think it's fabulous - although there were some spelling mistakes (tee hee). As I look below, I'm not sure what identity to post with. We'll see if it works :) XOXOX
