Just terrible. No words, really. My third child is 5 months old now, and even after 7-1/2 years of parenthood I still go upstairs every night to make sure he's still breathing. And my heart still skips a beat if I don't see his chest expanding soon enough. I can't imagine the sorrow and the complete grief so many are feeling in China right now.
I cannot imagine the kind of pain those parents are feeling. I watched some post-Katrina footage last night on youtube and the OP is right, the hurt is just as real no matter where it takes place. Hug your kids tight, and never miss the opportunity to tell them how much you love them.
Words fail me. As a parent, this suffering is too horrible to even comprehend. I hope these parents can find some comfort, some how.
