Dear Vivbass,
I have never ever bothered to forward these 'chain' mails ; I simply dump them in 'trash' ! No letter can affect the blessings which God has in store for us. No mail is more powerful than our prayers,

our good intentions and deeds. Don't worry over what harm would come if u don't forward some silly words; they are just using God's name to frighten poor souls into doing things they don't really want to do. Sometimes the excuses & punishments are literally laughable ! If it's a close friend you can politely tell them, u don't believe in all this & not to disturb u by sending such stuff.
If not, try forwarding the message 10 times to the sender itself ?

Get rid of them in one shot ...
With love,
Dew.
