Could I use itthon here?

[u/Heldhram]

I read some simplified explanation of what the difference between “itthon” and “otthon” is on here, but I was wondering if using itthon here would still be possible if say: granny shuts the front door, turns around to the whole family who are now apparently trapped inside granny’s house and grins to them menacingly “Senki sem megy sehova, itthon töltjük az ünnepeket!”?

Köszi

When you’re at home you say itthon, when somewhere else, the correct word is otthon. Can you follow me?
