I love a good thunderstorm me. Huge crashing peals of thunder and the whole sky lit up, fabulous.
It's coming down stairrods too*. I did consider dashing back from the library to chambers, but decided against it. As I did against the third way: taking all my clothes off and cavorting naked on the lawn. I don't think the Masters of the Bench would like it.
*[ETA: The raingod evidently took that as a challenge and decided to show me what they could really do. Anyone know a courier firm for umbrellas?]
