It really depends on a person I'm talking to. I definitely don't push anything on anyone, but if someone shows interest I'm happy to share all I know.
For folks that are like "why would anyone need it":
  • I show how I can exchange USD for another Fiat with much better rate than any company provides, often literally gaining 2% extra (and all of this is internally using Bitcoin+LN, but I sort of mention the Bitcoin stuff only in the end)
  • I show how you can get 8% cashback on any Amazon purchase.
For folks that are like "this is a stupid idea, we already have dollars":
  • Same as @k00b I spin it through the how money works
For folks that are interested in "what it is":
  • I start with how it's valuable money that you can send anyone in the world (and show some LN transaction)
  • Then talk about how there's 21M, the tech is getting constantly better(how many new features did your gold gain over the last year?) and the implication of that is clear.
And I think that's all I experienced so far :)
One note: Outside of Bitcoin world, no one knows what is "ledger".
