Yes, many people did not know my jw was one for a long time. After they found out their first response 9 times out of 10 was, "I thought he was smarter than that". sigh, explain cults, etc....
I also am always waiting for some shoe to drop on me and hate the feeling but have learned to live with it. Helps to come here and find out what is going on in the org.
Jgnat is right! do not point out what they are not supposed to be doing unless it is something obnoxious and annoying to you, ha! that works sometimes, I would elaborate but had to use it just recently so I shall leave the long list of no-no's to the readers imagination.
