I read formally you need to quotation mark quotes. But for informal writing, its ok to forgo quotation marks?
Ex: he told me go. (formally it should be: he told me, “go!”.)
Not in my opinion.
However, "He told me to go" is fine. It becomes reported speech.
Formally, it should be He shouted,"Go!"
Don't forget to use capital letters.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
