Know what else I learned in Tucson?

That when your daughter calls you on her cell phone, don't answer with, "Hi, Sweetie.  How are you feeling?"  It might not be your daughter.  It might be David, the guy at the front desk calling on her cell phone to give you an update on your daughter.

And you might have to meet him one day, too.  And he might remember that you called him Sweetie.
