ME: It'll make much more sense to connect this computer to your DSL also so you can keep on top of updates and do your work from this computer too.
CLIENT: I've heard /bad/ things about the Internet. I don't want it in my house.
ME: But your other computer (her daughter's in her bedroom) has the Internet and your whole family uses it (including the client), so it's already /in/ your house.
CLIENT: But this computer is MY computer in my house. So I don't want it on there.
ME: But that doesn't make sense. The only change from your current situation will be to make things easier for you.
CLIENT: I don't care! I don't want it!
