I think my dad's a bit the same with all the crime scenes he's been to (he works for the Forensic Science Service) He always sounds so detached and professional when he talks about blood spattering evidence, semen stains on knickers, etc, but he must have seen some really horrific things over the years. He does the same thing of navigating round an area by all the murders and rapes that have happened there - it spoils places for him because he always sees the seedy underbelly. I often feel the world is divided into the people who have seen death (like my dad, and my boyfriend who's a doctor), and those (like me) who haven't. We can't properly understand, I don't think.
