When I was active with the JW...an old friend sent me that one with the testicles handing on the door knocker. I was so offended, that I told her I would never talk to her again. That was 4 years ago. Now, I kinda regret it. I don't like things like that anyway, but I was offended for my faith. Yeah, come to think of it, lost a lot of friends while I was active...
I just have a little "do Not Distrub" sign I hang on my door all day anyway.. I have M.S. and never feel well, anyway.
