For me, it has more to do with what they might use the information in a way against me rather than to know it to help......which is more of a trust issue with me......where someone I don't know on the street doesn't know me or the details of my life to the point where they could use it against me.

Or they tend to think they can figure out in their own mind things that can help & then they want to force their ways on you.....but someone on the street just isn't going to do something like that so it's safer saying something to them because it won't come back to bite you.

That has been basically from some of my experiences.

I to love having friends who I can feel safe enough to share & be very open with......that's the most wonderful & comfortable feeling...but it takes time to continually test the waters to make sure that it's safe to share....& it seems like there is always going to be some friend who thinks they have ALL the answers & will make sure that you know those answers & that you should be following them......boundaries aren't always easy....but learning boundaries & being able to enforce them in my situations has been key being able to share more.
