Nostalgia is an emotional response / mental state that has been a sort of fascination to me for quite some time now. I have noticed that it is seemingly impossible for any one person to define it or describe it in a way that everyone can relate to. Nostalgia is highly specefic and very personal for everyone. At times it can even be diffucalt for one to describe or understand nostalgic feelings to themselves, they must resort to saying "this is a very nostalgic feeling". The ways at which things trigger nostalgia then is even hard to describe. It sort of just happens. It makes sense to everyone, but at the same time nostalgic feelings are quite intriniscly irrational, in the sense as they can appear out of the most trivial things. So, my question for all of you, is what is nostalgia like for you? How do you experience it, how would you describe it, can you describe it? Discuss.
