Similarly to the 9/11 attacks, it seems that the importance of the London attacks didn't hit me until several hours after they happened. For 9/11, it was when I first heard "The towers are completely gone." For London, it was seeing all the posts on my friends page calling out to make sure people were okay.
My heart goes out to all of you, and especially to all those caught in the blasts.
My mind right now is on my friends in the London area, but I do have one thing that's buoying my spirit in that regard right now: How many people on LiveJournal have to get up and get to work at 9 in the morning?
