As soon as I heard that noise I was up out of my chair and racing breakneck through the house to the door. I wanted to catch that blue box, bluer than blue, before it went off. Maybe I could go to this time.

But no, there was no sign of it anywhere. And trust me, I looked. Upon returning to my door I saw a small box leaning nonchalantly beside it, like the most natural thing ever. Lifting it up I sniffed at the sides, shook it just a little, and wondered at what was inside.
