"You must be old." Well perhaps. Relatively speaking perhaps.

"That SF was long gone before I and most people I know showed up."

"Even my wife, an SF native, doesn't have such nostalgia."

Well you don't know any different then and have nothing to compare what is now with what was then. If all you know is what is there now, then I suppose I feel sorry for you.
You will have NOTHING to be nostalgic about.

I don't know, nostalgia is a very personal thing.

I'm already nostalgic for a lot that has changed in Manila, and SF is about 243x better than Manila.
