I don't understand

First of all if any one reads this post please understand that I am really not sure what Ben Peeks Understanding entries are meant to do. From what I gathered in the two understanding entries/pictures is that even though G's death hurts and depresses him Ben Peek he has to understand that G is gone.
I think that the second understanding post is what really helped me figure out what I thought the meaning of The two understanding posts were. It shows Ben Peek looking over after waking up and seeing that G is not there. The picture shows that G's spot is imprinted on the bed next to Peek. I think the eyes in the first entry represent his look of sadness and understanding that he is expressing in the second entry on understanding. It is doubtful that after G has been gone for so long that there is still an obvious imprint of her presence still on the bed, but the picture is meant to help the reader understand what Ben Peek is feeling. I think that the first entry of the picture of the eyes is purely a connection to the second entry, just more intimate.
I think that using a picture like Peek does in the two understanding entries can truly help the reader grasp his feelings, and also visualize what the characters look like. With out a picture the whole message the Peek is presenting could be presented too directly. Finally if I analyzed this at all correctly then the two pictures are used simply to help the reader understands Peeks thoughts.
