Speaking for myself, this whole event has effected me far more than I suspected it would, even watching as I have from my living room. I can hardly imagine seeing it in person.
I think many of us have been experiencing the same thing over the past five days. Even though we knew he was no longer 'with us,' he was physically here. Now that he is not, there is a void that cannot be filled, because no one else is capable of filling it.
