Is the following statement grammatically correct?
"I'm loving isolation. A little too much."
I think the statement is grammatically incorrect, but someone, a professional writer/editor, made that comment on Facebook, and after I called them out on it, insists that it is correct.
I see that it is trying to replicate natural speech, but the way to introduce a pause would be with a dash or an ellipses, not a full stop.
So which one is right, a period or something else?
