So did you tell him what questions specifically? He might have run it by an elder (or another elder) who told him to skip it. They prefer to drop by unannounced I think to catch you doing something bad.
But remember the WTS says that if the person isn't entitled to know the truth, it isn't lying, right?
The elders are lying all the time...my husband said that when they got BOE letters that many times there was was the elder version and the congregation version (minus some interesting but embarassing points if the rank and file knew). As a new elder, he felt it was lying but was assured by the older elders that it was the right thing to do, that the congregation could not handle the whole truth.
