I don't think I would pass on anything I overheard, something that happened away from me and that I was not part of and might misinterpret. There were others who were part of the conversation who could report "better" if necessary. A conversation one can't quite hear, about a subject one can't know what it was about or its context is "dangerous" grounds to be reporting on.

If I saw someone in a self harming action or attempting suicide, I would step in and one-on-one interfere with that person's action. If someone told me they were going to self harm or kill themselves, etc. I would advise they get help and help them do so if they wished but I would not presume to interfere in their lives and decisions. I would not look at you, decide you looked like you were thinking about harming yourself and call the police?

But I don't think that it was wrong of you to tell the mother! My point is just saying you have to decide what []i]you[/i want to do in the future to avoid feeling as if you were misunderstood. You can dial 911 if you think that is a good idea! The mother didn't like what you did though and felt you had crossed her boundaries. I don't like other people accusing me of boundary crossing because it means I probably have and I strive not to do that. "Wanting to help" is not a good enough reason to go ahead and "help" if another person doesn't want or need one's help.
