I think this quotation is clear in it's meaning, because we have all likely experienced a situation or read a book or saw a movie that made us realize we don't always understand the whole picture, even when we think we have all the information. It can be really hard to look past the obvious and consider what the truth of the matter is, and how we react to that truth.
I know I often have to try and look at difficult situations through the eyes of the other people involved, and employ a sense of empathy in order to fully appreciate how everyone feels and to ultimately come to a resolution.
I am reminded of many works of media and fiction when I hear this quote; in fact all of the texts and film we study in this course are strongly connected to the ideas I'm discussing. The movie "Inception" and the novel Atonement are very much concerned with the themes of perception (and misinterpretation) and looking closely at the circumstances and deciphering the truth. And especially what it is then, that the characters do with their concept of the truth in specific circumstances that becomes central to the outcome of the stories...I don't want to give too much away!
