those pictures that are essentially saying "stop complaining, you're not getting shot at like I am" are annoying. I recognize that your every day tasks are potentially more life threatening than mine, but getting on your high horse about it is unnecessary. We all deserve a forum where we can vent about our stresses, no matter how meaningless they may be at the end of the day. A little perspective is nice, but don't be a self-entitled jerk about it.
If you have friends on Facebook who are in the military, you may have seen some images like what I'm talking about.
