Tell the person that the nature of the business is related to selling .ws domain names which include hosting, a site builder, and email accounts. That .ws is becoming the next .com domain extension. You can say the business involves introducing other clients to .ws domain and hosting package and that they earn commission for every person that signs up for their own personal or business website. That for $10 a month they are getting a website package and an income generating business as well. They get Two things for one price.
I would suggest using the word "promoting" or "marketing" instead
of "selling".
When I am asked, I say, "I get very well rewarded for showing
people how to make make additional income."
Very often I will get a response, "Okay, so tell me more".
I then say, "Got a card?" If they haven't got a card I produce
a pen and a pocket sized spiral note pad and say, " jot your
name and email address on that and I'll send you some
information." I then log in to GDI and use the invite system.
I try never to get into conversation about the detail, nature,
(or anything else) to do with GDI. I let the tools do the
talking.
Hope this helps,
Gordon
