I so wish I had my camera with me today...
Bright bright sunshine
Dark clouds on the horizon behind the white Wren buildings of the Old Royal Naval College
Sudden rain out of a sunny sky
A group of foreign exchange students in bright clothes with lots of brightly coloured umbrellas sparkling in the sun walking along in a long 'crocodile'.
moral of the story - charge my digital compact and carry it in my handbag at all times.
