Just a quick update on Mark. We were finally able to talk on the phone briefly a few minutes ago. He is completely worn out and battling a cold/laryngitis-type thing. He thankfully made it through his paper presentation yesterday and thought it went well, though due to a weakening voice I didn't get many details from him.
He thought of coming home early, but I checked on that possibility for him and there aren't any seats available on several of the flights, so I think he'll have to stick it out until Tuesday. Please pray he can get the rest he needs today and will start feeling better soon! So hard to hear him sounding so pathetic when I can't help.
