Very dark clouds rolled up about 4.50pm and it began to absolutely piss down as I walked home. Glad I started keeping that spare brolly in the office. Actually I still got soaked from the knees down, it was raining so hard, but it makes a big difference when your head's dry. Once I'd got going, it was very pleasant to walk through the rain, see the gutters in full spate and huge puddles everywhere.
