Watching the Christmas episode of Dr Who was struck by a quote. No spoilers in case you have not seen it but it described how we tried to live our days when we knew that whatever we did Estella was going to die. How could we act normal or enjoy time with her ? Here is the quote.
"What's the point of them being happy if they're going to be sad later? The answer of course, is that they're going to be sad later."
