Maybe it is a "guy thing"? My husband is the same way too, he is like, "Well, people die everyday, so what is the big deal?".
From my perspective though, seeing a tragedy, I feel for the people who died, the people they left behind, their mothers, etc.
But, it irritates me to no end when I see people act just utterly devastated when celebrities die! Or even kill themselves because of it! Remember back when Princess Diana or even JFK jr. died, they were showing on the TV people crying and carrying on in the streets. Total emotional devastationover the death of someone they didn;'t even know. Get a life!
