Lashon hara. A colleague of mine is is asking about doing business and building a Relationship with someone I think is disingenuous and a conflict entrepreneur. I stay away from him and no longer keep in contact on social media. He is very enthusiastic about him. He asked me why I don’t have contact with him and why I don’t work with him. If I were to be honest I would tell him, but it would be mostly negative. However, he keeps pressing me and I feel like I’m being dishonest by not telling him what what I really think. He respects my opinion. How much can I say without it being lashon hara? Thank you.
