That's just me

Hate me if you like, but when the Boston bombing, the building collapse, and the explosion at the fertilizer plant occurred...I didn't care.  Other people aren't my concerned.  I care about some people, but not many.  It makes sense to me that my world is all I should care about.  What good would it do to worry about the Boston bombing victims?  It's not like I could do anything about it.  I have enough to worry about in just my world.
