<human>: Give me the gist of the text in a nutshell

I am currently a pre-dental undergrad.  Since I don;t know anyone who is a dentist personally, I usually have to cold call all dentists that have practices in my area.  Well, my university had given me a list of dentists that I could call about a year ago.  I called one location near my house this morning.
 
"Hello, could my name is ______ and I was hoping that I could possibly job shadow Dr. _______ sometime this week, as I have been told that he is willing to offer job shadowing opportunities"

"Well, that dr. isn't in at the moment, he ........."  

At this moment I knew the receptionist was upset.  She was clearly sniffling at the other end of the line........

"Dr. _____ passed away about a year ago.........(sniffle sniffle)"
 
At this point I used every version of "I'm so sorry, I didn't know" to salvage the situation, but it was no use.  The receptionist had started to cry at the other end of the phone, doing her best to hide it, but was clearly crying, and then started apologizing to me for crying as if she was the one who had done something wrong.
<bot>: Made a receptionist at a dental office cry because I tried to job shadow the dead dentist that used to work there.
