From the window of the house where we're staying in Wales you can see the sea ... technically. What you can actually see is a murky grey line which meets a slightly darker grey line - that's where the sea meets the sky. When the rain is particularly bad the 2 colours of grey merge and become one big grey nothingness.
When children draw pictures of the seaside they always draw both sky and sea in blue. I'm not sure why, especially if they've been on holiday to Wales. If I were still a child I'd draw a picture with a lot of grey in it. In fact I'd get a grey crayon and cover the whole page in grey. If I were a grown up I'd draw a picture of my wallet gaping open with a shower of £10 notes disappearing out of it like a plague of locusts.
On the bright side I've discovered Welsh Cakes.
