Back in the days I was in college, I used to work PT for a neuroscience professor part time. The job isn't a big deal... use a custom app to track animal brain waves, graph out the results, and submit them to the professor for his papers. BTW, the professor was 84 years old.
When they say you can't teach an old dog new tricks, it's definitely true. He has his own ways or organizing things, and it came to a head when it comes to email.
When he sends an outgoing email, he insists on BCC-ing himself a copy of it; apparently, clicking the "sent mail" box and looking at it is not an option; he wants everyone in the inbox. Therefore, when the BCC-ed email comes back to him, it looks like this:
From: Neuroscience professor
To: Neuroscience professor
One day, he came to me, and asked whether he can make changes to the email, so that when the BCC-ed email comes back it will look like:
From: The person to whom he sent the email to
To: Neuroscience professor
When I told him that doing such a thing is impossible, since that's not how email works, he comes back with "Well, you talk to whoever's responsible for email and change it then! I don't understand why it's not built this way; that's what BCC is for!"
So, I do my "support", which included calling our email client, university computer support, and having a good laugh with the tech support personnel when I brought up the problem. Eventually, the professor would have something else to do and we would move on. However, six to nine months later, he would bring up the topic again.....
