Yeah, having been there with a co-worker whom I didn't know very well, but respected for her knowledge and smarts, it hits closer to home when you realize you were one of the last people to see her alive, and there didn't seem to be a clue that something like this was going to happen. You mentally rewind and replay, rewind and replay, but if you didn't pick up on it at the time, you're not going to pick up on it on the revisit of the memory.
Yeah, I should get back to walking, now that I'm mostly better. I haven't walked since a week ago Monday.
