This misquote comes care of Sheila, a PoohMisquote Correspondent, who writes:
I am preparing the eulogy for a dear friend. She was a fan of Winnie the Pooh and I would like to include the often attributed to Milne quote, “If ever there comes a day when we can’t be together, keep me in your heart. I’ll stay there forever.” However, I want to be sure it is indeed a true Milne quote. Can you tell me if it is and which book it comes from? Heartfelt thanks!
Unfortunately, Sheila, this is not in fact a Pooh quote. It doesn't appear any Milne book or even any Disney film as far as I can tell. It is popularly mis-attributed to Pooh however, possibly because of the line in the Disney movie Pooh's Grant Adventure: The Search for Christopher Robin (1997), which begins with Christopher Robin saying "If ever there's a tomorrow when we're not together..." but ends with that quote: "You're braver than you believe, and stronger than you seem, and smarter than you think", (which is also so commonly mis-attributed to Milne). I can't seem to find the original source of this particular Pooh misquote - so please, someone, email me you know know.
Rather than just being critical however, I would like to suggest another Pooh quote about friendship that might be suitable for Eugoogalizers (to steal a term from Zoolander). The difficulty here is that most of Milne's original material was more about the story, and less about the aphorisms. Nevertheless, in Milne's "Winnie-the-Pooh" (1926), Chapter 9, which is entitled "... in which Piglet is entirely surrounded by water", Piglet finds himself trapped in his house after days and days of rain, with the water nearly up to his window. "If only," he thought, as he looked out of the window, "I had been in Pooh's house, or Christopher Robin's house, or Rabbit's house when it began to rain, then I should have had Company all this time, instead of being here all alone, with nothing to do except wonder when it will stop." Then, later, Piglet has the wonderful idea of sending somebody a message by putting it in a bottle and throwing it out the window. And then he gave a very long sigh and said, "I wish Pooh were here. It's so much more friendly with two."
And there's your 100% genuine, accurate Pooh quote for eugooglizing: When trapped in a house for days on end, surrounded by water up to your window, it's so much more friendly with two.
And of course Piglet's message in a bottle IS eventual found by Pooh, who DOES go on to rescue him, with help from his other Friends, travelling by upturned umbrella over the waters.
