Well done, its always fun to stick it to them, especially when they ask!
Nothing wrong with polking fun at their stupidity. I remember one time a witness (a very selfrightious arrogant one) my wife and I knew said hello to my wife while ignoring me because he knew I had left the JWs. I said: "WHAT AM I INVISIBLE?" he was embarased and my wife gave me a dirtly look. I was laughing at the guy while at the same time thinking if says anything I'll let him have it. I was thinking what kind of arrogant bastard would think it was ok to come to someones house and ignore them. I was ready to tell him if he couldn't show common courtesy get his f'ing arrogant ass off of my property. Fortunately he just left without sayig anything. My wife was pretty upset with me over the incident.
