eltekett@gmail.com Elena From Russia--Who Is This Person??

I am not sure I'd classify this email as a scam but I'm wondering what the real story is behind this type of email shown below. What is interesting is the person who emailed me is supposedly named Elena but she (or he) is sending the email from the header as green.eugene33@hotmail.com if you choose to reply to the email or eltekett@gmail.com if you wish to email her and not click on "reply".

Has anyone had any experience with these types of emails and replied out of curiosity? And if you did reply, what did you say and what else did you receive back by email?

Now...on to the email message:
