Oh... I'm surprised that doesn't happen more often - being enclosed in a dome like this. I'm sure when people get sick, it spreads like crazy. [ A pause; that's probably not the appropriate thing to say. This guy is obviously upset even just remembering it, so it's probably better to just distance himself from the topic. He'll change the subject. ]
I mean- I can only assume, of course. I just got here the other day. How long have you been here?
