I don't pray either per say, but I do want to thank your nephew and his fellow comrades for making sure guys like me, for example, can go to college without fear that my dorm will be blown up. It disgusted me reading about all the bombings when this war in Iraq first started, and I'm thankful that doesn't happen around here in America, and I can thank brave souls like your nephew for that.
Definitely will be in my thoughts, and has my best wishes for a full recovery.
