Hexed or Cursed?

I received this e-mail from a friend. At least, I think she's a friend. But I don't know why friends do these things to each other. The e-mail reads:
An interesting fact about October 2010:

This OCT. has 5 Fridays, 5 Saturdays and 5 Sundays, all in 1 month. It happens once in 823 years. These are considered money bags months. Pass them to 8 good people and money will appear. Whoever stops this will experience none.

With Halloween looming, it gave me goose flesh and made my skin feel cool and clammy. So I replied to my friend (at least, I think she's my friend):
Ashley,

Did you just put a curse on me? Even with five Fridays, five Saturdays, and five Sundays this month, I don't have time to send out all these e-mails in hopes of receiving a fortune, much less to cope with a curse. A hex is one thing, but a curse, of course, quite another.

Here's the difference:
A curse is a malevolent spell that is purposefully done to inflict harm upon another.
A hex is a spell or bewitchment that can be done for good or for bad. A hex is generally less potent than a curse.

I think it's important to know which kind of e-mail she sent. What if I was due a bag of money this month anyway, whether or not I ever opened that e-mail, BUT, because I read it and didn't forward it to 8 good people, I'm now no longer entitled to receive my money bag. That would be a curse.

But if I read it, ignored it and consequently turned into a frog, then that's a hex.

She replied to me:
Heavens, no. None of us needs a curse. We have far to much to do & accomplish and no idea how to get it all done...


I guess that means it was a hex and that I'm a frog. 

Why do friends (at least, I think she's my friend) do these things to each other?
