Joseph – lol, I had a feeling someone would say that. I was just wondering who it would be. It could be, but the question is if halachically it’s information I can give over since it can harm someone. It might fall in the category of private information that I’m not supposed to be revealing. In my case, I was particularly concerned because they had specifically given me a special deal (not what they initially advertised) for specific reasons.
I also wonder if halachically it would make a difference if we are talking about a situation where I know I am moving out and I am talking to a friend who wants to move in and I want to help her out (and the landlords would realize that I would be likely to give over this information) versus a case where I have no immediate plans to move and/or I am not talking to a friend who wants to move in and I am stam spreading this information that my landlord might consider to be confidential information (which is the case I was talking about).
