Guilty of carrying on normally

I carry on with my life as if nothing has happened. I understand mourning is not a solution to the terror problem, however, I fear that a cloud of insensitivity is trying to overcome my humanity. Is normalcy taking over the good sense? Or, have I started defining good sense in a different way?

So, what can I do?

• Not laugh at the insensitive jokes cracked by others.
  
• Be more alert.
