I have a couple of questions about commas.
If you quote a short sentence, can you omit the comma after the dialogue tag as a matter of style?
Whenever I come home, I always say "Honey, I'm home!"
Is the comma after "say" in this sentence essential? I like the way it reads without it.
When you have a modifying phrase after a location within a location, do you need to use a comma?
I visited Tokyo, Japan last summer.
I have seen some sources say this version is correct, while others have said I need a comma after "Japan."
