This is my grammar doubt.
The sentence is: When must I make my decision?
I think it's too formal, because the speaker is supposed to be a low class woman, isn't it?
Would it be correct and more informal if we said "When do I have to make up my mind?"
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.
