When they come dont answer the door. Isnt that what you are supposed to do when JWs come?
The nanosecond you open your mouth...you will be DAd or DFd because first of all they have already formed an opinion about what you are doing and second of all once you start talking its going to be like pulling the plug out of the dam...its all gonna pour out of you.
Dont say ANYTHING. Nod...pretend to be interested in their council, tell them you will see them at the Hall. Close the door.
