future nostalgia

I was having a conversation with a friend of mine last Friday and she was telling me about one of the times she's felt the happiest and most fulfilled. And that at the time she felt future nostalgia. Nostalgia you know you'll feel in the future for the moment that you're in. Thought this was profound. Anyway, this pic makes me feel nostalgic. A nostalgia now rightly felt in the present for the past. but at the time I'm sure it was the other way around...
