I cannot stand Public Mourning Kabuki.
I hate the "make-shift" memorials, the teddy bears, the little notes and flowers-I hate it all.
Yes, you can be upset about a bad news event. But no-it's not about you, so you have to compartmentalize it, and if you are a mature adult with a real life, then you realize it's not YOUR SAD and get back to your real life.
It's someone else's sad, and it's really for them, not for YOU.
