I agree. I think you did good. The only thing I would say is that I probably would've cut the conversation short earlier. (be the first to leave yadda yadda). Like "wow, that must really be awful. I hope it all goes well. Have a lovely evening." Or something. My brain isn't really on point tonight. I woke up out of a dead sleep at 5am (still dark outside) and couldn't go back to sleep.
