Answer 1

I don't understand.  Who is Nancy and "Nancy's ..." what?  Did you miss a word out?

Answer 2

Some people, usually (but not always) older people are creatures of habit and don't like change. They prefer to stick with what they know probably out of fear what they know will become obsolete and they won't be able to understand how to use the new technology.
