Ever since the birth of my son I developed a repulsion to the news stories of kids being hurt or abused. Before that day, even during the pregnancy I knew these things were bad but I would barely allow my brain to think "that's a shame". 
I believe this to be the same for everyone who goes into parenthood. So when I hear a story like 'baby P' I avoid because even it's existence makes me queasy with rage and maybe heartache.
However this still leaves famine, homelessness and Aids as something I stare blankly at. I'm sorry.
