It turns out Chris had mentioned it on the podcast that noah linked. But it really would have been better if he had said something like: "Chris mentioned on the podcast that his daughter has been hospitalized...I think we should let him know that his CF family cares."
The way it was worded, it reminds me of one of Lew's sisters, that ALWAYS has to post on FB any time she hears someone (sibling, aunt, uncle, sister-in-law's cousin, yadda yadda) is sick or in trouble...complete with salacious details. She HAS to be the one that "knows everything". Drives me crazy, and Lew and I never share things with her any more.
