To post or not to post......

This is a common question among writers who are writing their memoirs.  Do I mention characters in their direct relation to me?  Do I post their pictures?  Just how much personal information can I comfortably share?  What about my kids, how will my honest interpretations hold up in the reality of who their mom is? 
The true answer, is in the subject of personal growth, of which my writing material is mostly about.....honesty is the primary rule.   But to what extent?  If someone is offended, it is an opportunity for their own internal self exploration, but what if their are not ready for that, and being offended is the only space they can hold at that time.
I just had to post my niece's picture here, because her sweetness saved me a couple of days ago, interrupting me as I was going through the density of my journals, nearing the death of my second husband. Is it suicide if he chose to drink himself to death?  Now I know his mother, sweet, smart, 92 year old Jo, may be offended by this remark...but I know she doesn't have a computer...or does she?

So for now....I seek permission, if flags are raised, and write carefully.  But when I am 92....I won't give a damn.
