Last night during Veneration of the Cross, he was testing the properties of candle flame ... how far does the heat reach, compared to the light, compared to the distortion. Is it different from the top or from the side? What if I turn the candle this way, or that way?
Fortunately, no disasters occured. I would catch his eye and gesture “holding the candle level in both hands,” and it would go back in place until he had another thought ...
