The last candle
The power went out. Not unusual, it happens every day. I had just set the kids up with my laptop, though, and they were clustered on the couch like pigeons, watching a Pingu episode. My laptop has no battery (meaning it's pretty much a desktop) and the kids wanted the power to come back on. It was not obliging.
Leafy kept asking me to light thus last candle.
See, my Superstar husband always says that the power comes back on as soon as you light the last candle. Naturally Leafy wanted to skip the preliminaries and light the last one.
