Should we cry or should we laugh?

Years ago we worried so much about AIDS and now it's a common house hold word that we talk about during dinner. Then we live through the horrors of the 9/11 ordeal, which still brings chills to my spine. Now we have hero's, like the plane that hit a flock of birds and safely landed in the water savings lives. Now we are hearing about the swine flu which has already hit America and I feel we should have heard about it before it ever crossed over into our lands. Now today I read in the news about a plane not yet flying but sucks up a luggage ben into its engine and scaring hundreds of people. So O.K. should I laugh or should I cry?
