"Friendship" emails

I don't know about you, But I really hate getting those soppy, pointless emails from friends and family that say things like "I'm sending this because I care". It is so pointless, because if someone really cared they would have created a message themselves and not just forwarded a (twenty) generic email(s) that they had been sent to them.
My sister Maxine is a prime example of someone who forwards every single one of these stupid, pointless emails. I'm sure she means well but this morning one of the five that she sent me was really quite sinister. It gave 2 examples to start of people who hadn't forwarded the email (or who hadn't forwarded it to enough people), they both died horrific deaths!
Firstly, I don't believe this shit anyway, I mean has good fortune only existed since email was invented?
Secondly, if these two people died for not sending the email, how come they are mentioned in the email?
I found the threat of this email quite sinister: Send this email to at least 5 people or you will die a horrible death! Nice. Thanks a lot sis! Just what I need on a Sunday morning when I'm trying to sort out my working life that's going to shit!
