Drove down to Ma's earlier to sort some paperwork for her. It was rather nice and sunny, so I left the sunroof open a couple of inches to ventilate the car, parked up and went inside. About an hour later, there was 10 minutes of monsoon... No reaction from me, other than to call Henry (dog) inside. Another hour further on, another mini monsoon - with hail. About 5 minutes into this one, I realise the fucking sunroof's open. BUGGER!!! Thank fuck for leather seats, though...
