Seeing from the inside out

A wizard (not that it matters, you genre snob) discusses 'the good old days' with an equally elderly witch...

"Everything was a different colour in those days,"

"That's true." 

"It didn't rain so much in the summer time."

"There were more old people. The world was full of them," said the wizard.

"Yes I know. And now it's full of young people. Funny, really. I mean, you'd expect it to be the other way round."
