So I was reading @-sarcasticsalma 's book Ravenclaw - rant.b (if you haven't read it please do as it's amazing) and there was a chapter about how weird it is that lots of Jily books are called 'Always'. So I commented saying that I agreed it's a bit odd seeing as always was Snape's thing. When SibunasAtHogwarts pointed out that perhaps James started 'always' and he forgot to copyright it! Now I don't really believe that James started it but it's a really cool idea, it makes me wonder if there are any famous quotes by real people that everyone raves about and thinks is so original but the famous quoter (if that's a word) didn't actually make it up.
