Parallel Shadows

Out skiing again on the same lake as yesterday. This time we took a bite to eat, a flask of coffee and something to sit on, as relaxing in the sun with a minimal picnic is always fun, as well as providing an energy boost for the trip home.  We skied a little further than yesterday and found a jetty to sit on and watch the sun go down as we ate our snack. 
It was now HarlingDarling wondered where the biscuits were, and the extra thermos cup, and I wondered where the bananas were.  We came to the unfortunate conclusion that they were forgotten, still on the kitchen table.
If you are of a grammatical turn of mind you may have noticed the use of the passive form there; they were forgotten. HarlingDarling definitely noticed and reminded me quite forcefully that actually I had forgotten them. Fortunately I had thrown in a  couple of chocolate bars at the last moment, otherwise my popularity rating would have sunk through the ice, down to the muddy depths!
The title of this Blip is "Parallel Shadows" and all shadows from a light source 150,000,000 kms away must indeed be parallel. But here (and on the ice) they actually look as if they are fanning out. It took a bit of discussion with HD and her artist's knowledge of perspective to figure out why it is so!  Think about straight and parallel railway tracks disappearing into a single point in the distance...
My apologies for introducing a bit of grammar and maths into my blip. It's a work related injury that ex-language teachers of a mathematical bent often suffer from.
