Just being facetious:

So let us say that tomorrow you wake up realizing that you forgot to tell him about your extended family - uncles, aunts, cousins twice removed with their young babies, etc. - who all play an important role in your life and will all be visiting soon - before Christmas - and that you expect him to entertain them and change the diapers of the babies (cousins twice removed have babies who need diaper changes).

And when he asks you questions, tell him that he should be grateful that the extended family visit won't last long - they will be gone after two months. And then won't come back for another year.
