I agree with you, Dad.

You had to cancel your camp out, because your wife stayed out till 3am.

Was it decided beforehand that she would have come home early?

I think you did the right thing, and have every right to be annoyed.

Sounds like mom was just being selfish in staying out that late, or just genuinely forgot about your camp out plans. If that's the case, no need to be mad, it's a mistake. :-)
