Everything is hunky-dory

It means 'everything is fine because you got home safe', just like the expression 'okey-dokey'. 

Here is some more information from English.stackexchange.com

The least exotic theory of all, but almost certainly the true clue, traces "hunky-dory" to the archaic American slang word "hunk," meaning "safe," from the Dutch word "honk," meaning "goal," or "home" in a game. To achieve "hunk" or "hunky" in a child's game was to make it "home" and win the game.

The question of where the "dory" came from brings us back to our old friend "O.K." Children very often do not just say "O.K." -- they say "okey-dokey," thus engaging in what linguists call "reduplication," or the emphatic, joking repetition of parts of a word. "Hunky- dory" is almost certainly a similar product of reduplication by children who had won their game.
