Thanks everyone for your replies,
undercover, yea..I threw the invite away after tearing into bits- it was just curious to me because everyone always made a big deal in our Hall about "no trespassing" signs- they would say that the society could be sued for violating those signs and that would bring reproach upon Jehovah, yada yada BS BS.
wasblind, I do not think you are paranoid-someone in your cong wanted to make a point in a passive-agressive way- yuck..
everyone in my Hall knows where I live, so personally I think it was left there knowingly "to reach me". The car group probably smiled all day at the possibility that because they left that invite in my door I would be moved to tears and come running back to Jehovah's organization
