Every year, when it comes time to get out the Advent wreath, I waste precious brain cells trying to devise the least wasteful candle-burning algorithm. Ideally one that makes all the candles appear to burn at the same rate.
If only I had never bought the wreath that takes spherical candles.
And every year, late in the evening on the last Saturday in Ordinary Time, I hope that I put new candles in the box before I put it away last year. Every year I open the box and wonder why I left one candle in there melted down to a stub. And every year I vow to burn the candles more evenly, so that all four of them will be re-useable the following year. And yet I have never managed to do so.
