Hi guys... Sorry about the weird title. I just didn't know what to write as this is such an odd question. I'm writing an argument between two sisters and one of the sisters is accusing the other of ignoring her. Their parents had died a while ago and they've become estranged. The more timid sister says this to the other, “I agree to that, for the first year. Then you up and just ignored me.” I'm having trouble with that for some reason and I really want this line in the book (I have no basis for why, I just like the frustration in it). But the problem I'm having is that in English there's a way to phrase someone saying that someone left suddenly, "...just up and left." Would this make more grammatical sense if I said, "just up and ignored me." or can I keep it the way I have it now?
