A blah email

I get the oddest spam. Here is an email I received in my spam/bulk box:

---

From: "Robert Wright" [e9cMartin@blogs.com]
Subject: Re: HI

blah

blah2

blah2

Sadly, I sometimes get emails from actual people that sound a lot like this. I wonder, what does the "blah2" mean? There must be some existential reason for the blah2 and the line break before it. And who is this Robert Wright and why is he emailing me a blah email? There isn't even an attached virus to attack my hard drive.

Most curious.
