Life changes fast.
Life changes in the instant.
You sit down to dinner and life as you know it ends.
-Joan Didion, after witnessing her husband's sudden death
I'm glad to know she's okay. Those kinds of stories freak me out... if you had been my mother, she would have had a heart attack before finding out that I was okay in a situation like that. When she lost my father in a sudden accident, it changed her whole response to these kinds of things... she has to hear from me nearly every day, and if not, she has a panic attack. And by watching your thought process, I can understand more of why.
All those what-if's... I know I could lose my husband in a simple accident every day, if one small thing goes wrong somewhere beyond his control (e.g the truck overturning on the highway). He could lose me the same way. Things like this are what remind us to be grateful for each day that passes without tragedy... and yep, what The_Jazz said, to keep in better touch when we're away.
