Something bothering me

Deception. Sometimes obvious, sometimes subtle. I got a forwarded email yesterday that promised me riches and fame if I passed it on to my friends, and also said unmentionable peril would come into my life if I didn't. I pray the well-intentioned people who send these things don't actually believe them. They are nothing more than modern day superstitions. One from a friend instructed me to send the email to all the people I care about, and if she didn't get it back from me, she'd get the hint. Do my honest conversations and smiles, and the laughs I share with this friend not indicate my true friendship? Does she really need the reassurance of a mass email that is frought with superstion, false promises, and ridiculous threats?
