How students see e-mail

Female Science Professor posted today about her reaction to receiving communications via the US Postal Service rather than e-mail.  Through discussions with my students I am increasingly convinced that they see e-mail the same way that I see snail mail.  For example:

You also couldn’t have known that I seldom look in my mailbox anymore. When I do get physical mail, most of it is junk mail. It is quite miraculous that I glanced at my mailbox this week, when I wasn’t expecting anything interesting. In fact, even once I saw that there was something in my mailbox, I almost ignored it, so sure was I that it was not important.
