Hi Anon_SA1, It is probably a lost cause asking your friend simple questions for the last time, unless your friend already feels resentful about how the Watchtower/elders/other JWs treat her.
How about asking her, " Why are you a JW? Is it for social reasons or Watchtower doctrine? (wait for a response) What would cause you doubts about being a JW? (wait for a response)"
If she is a social JW, then ask her "Why are you afraid to have more fun as a non-JW? (wait for a response) {List things that she enjoys that JWs frown on JWs doing] Aren't you tired of being asked to do more or wait on Jehovah when you see that something should be changed now? (wait for a response) What miracles has the Watchtower done to prove it is Jehovah's Earthly organization instead of another religion, like the Catholic Church?"
If she is a a JW because the Watchtower has the "Truth", then ask her, "What miracles has the Watchtower done to prove it is Jehovah's Earthly organization instead of another religion, like the Catholic Church? (wait for a response) What "Truths" has the Watchtower instructed you about that you couldn't have discovered by reading the Bible and discussing with your friends and family?"
Best of wishes.
Peace be with you and everyone, who you love,
Robert
