How do I know? He told me.
I called his home a few minutes ago and got his grandmother Linda (Cindy's mom), and first she told me Robbie's feeling good. She put Robbie on the line and told him, "Say 'Hi, Chris.'" Robbie said, "Hi, Kis. I'm cood." Meaning "I'm good."
So that's a relief. (I probably freaked out more than Cindy...)
