Just tell her you are a Catholic.
Yesterday, after Confession, I was walking in downtown. A lady approached me and asked me if I would like an Awake magazine. I replied "No, thank you. I am Catholic". Boy, she immediately stepped away quickly and said. "Okay, thank you".
This isn't the first time that has happened. In fact, my brother's Southern Baptist father-in-law, will tell JWs he is a Catholic, so they will leave him alone.
Does that happen to anyone else?
