OnTheWayOut,
Yeah, good thing you didn't get those ones (unless she didn't know what the books were about). You never know if they would tell the elders. I couldn't see someone being that nosey and annoying. Gossip is what would spread the news probably.
Isaac,
Yeah, when I run into a JW, I am too nice. I sort of want to run into one again too so I can have a second chance. When I ran into the woman at the grocery store, she only asked how my brother was. Next time if someone asks me that I'll say, "Actually, my whole family is doing great. Thanks for asking." (If you don't know it's b/c my parents aren't JWs anymore) I mean, didn't she realize that it was an insult? It made me feel like they just pretend they don't exist anymore.
Also, I think that this would be fun to do if anyone wants to. If you run into a JW who confronts you, you could look really confused and say, "Sorry, I don't know who you are. I was in an accident a while back. There was memory loss and I'm still in the process of recovering. How did I know you?" But I mean you would have to do a really good acting job. I don't think I could do it with a straight face. It would be fun to do though.
