Switched on the irrigation system - an hour later it poured

The new grass in the courtyard - put in at huge expense and backed up by a fancy eco-friendly rainwater collection system- was looking parched after a week without any rain so I switched on the irrigation. Naturally an hour after a copious watering of the grass a huge, and entirely unforecast storm blew down from the mountain and we had forty five minutes of rain, hail, lightning and thunder. Digby would like to think he is a brave dog - but he isn't. We eventually found him hiding under the bed trying to make himself invisible to the cacophony outside. Wilf slept through it all.
