I know this is not Asimov's best, but off the top of my head (it's bean years since I read any Asimov), there was a scene in the later Foundation series where a character was about to go on a space trip for the first time and start talking about how great the space travel technology is, blah blah...

The problem is, in a society where space travel is commonplace, nobody will talk like that.

Imagine someone in our world buying an iPhone, and walking out, saying "Oh how great that we have a technology to instantly talk to anyone else in the world! I have the technology right here on my hand, isn't it mind blowing?"
