I broke down at the bit in chapter 13 where he leaves the photo of Lori behind. It struck quite close to home for me, I had to take a break.
If I had a single remaining photo of a long lost loved one and I had one final chance to take it with me or lose it forever, you bet I would take it with me. I wouldn't risk my life to retrieve it but he's not short of space or in a rush so it didn't make sense to me to just leave it behind.
