If I’m going to sue someone I never say anything, makes I’d harder to prep by destroying evidence, BleachBitting computers, shredding documents, etc.

I have threated to sue but ask if that person has $10,000 to $25,000 for a retainer for an attorney to defend the suit. Most people don’t have an extra $20,000 they can part with within 30 days of getting served, and that alone will be the moment of clarity needed to get the other person to think a little more rationally.

Speak very politely and quietly - which can be more intimidating that shouting.
