Sometimes to be at home is like a nightmare by Stephen King.

Maybe this isn't home, nor ever was- maybe home is where I have to go tonight. Home is the place where when you go there, you have to finally face the thing in the dark.

Oh Christ, he groaned to himself, if this is the stuff adults have to think about I never want to grow up

Was it possible to feel nostalgic about something that had never happened to him, possible for nostalgia to be taken in by the body as a free pathogen to infect the consciousness with stray sentiments? Perhaps, in his dreams, he had traveled back in time, or even drifted into another dimension of space-time and inhabited the body, experiences, and nostalgia of another. To even envisage so allowed the trauma of those lost moments, though not his own, to draw from him a certain envy for the entity in whose memories he had basked vicariously. . .Perhaps, nostalgia was a microorganism. . .the bacterium that infected. . . Yes. . .maybe he was sick.

No child should ever be too sad to play.

I guess everybody thinks about old times, even the happiest people.
