I think we all have these in our family's.
My daughter thinks she has all the answers-lives in a doctors office from one complaint to another. My son is a know it all too but with eyes closed. I do not speak to him - it's been 4 ish years. After my husband died (his dad) he wanted to tell me what to do -control my money & find all sorts of vault with me.
I have so much peace in my life with no more he said, she said. I live up to God's standards not man's. I just walked away & don't look back. On AU we have friends that pray for us-love us as we are-willing to help-and we have not even met-as God's Plan was all this time.
