Sydney Barringer jumps from the ninth floor rooftop. His parents argue three stories below. Fay's accidental shotgun blast hits Sydney in the stomach as he passes the arguing sixth floor window. Google Books
This doesn't appear to be exactly synecdoche as the window is not part of the arguing people. Anthropomorphism also sprang to mind but I am not sure that is the case here either. That there is an element of anthropomorphism or personification is not disputed, but I doubt that gives the whole picture, because besides the personification of the window this line also connects the window to the arguing people.
Also I don't think anthropomorphism is a figure of speech. What is this then? Figure of speech or some other concept?
