People suffer, they hurt themselves...people take their own lives. People die.
The most perfect time for their so-called closest ones to start victimizing themselves - honoring their dead by almost taking even this post-mortem spotlight, making the event about them. They make collages of joyful pics together with their newly-defunct, throw in the "they were always smiling, would have never expected this..." crap.
Why were they jolly around you? Maybe because they were fuckin' smart enough to know the sad reality: we are only wanted around when we are fun and seemingly have the power to entertain. When we need to spill our soul out from down under in the dumps, people run like rats.
So we smile to our loved ones on our way over the edge.
