Confronted to no avail

I was with my dad, sister and nephew this afternoon for lunch, we had a really nice time, we went to Golden Coral in Toledo Ohio. After lunch the subject of my nephew disrespecting my sister came up and how my dad could still spank him if need be( he is 5 feet 6 inches and he is only 13) any way I got to thinking about all the comments that I received on here the other day about how my sister and dad not speaking up to my daughter when she blew me off. So I spoke up and said well nobody said anything when my daughter was rude to me the other day. My sister looked at me and said well I guess I didn't notice that and all my dad said was ya that wasn't right. So I went on to explain to my sister what she did and my sister said well if it is bothering you, you need to talk to her about it. That was the end of the conversation. I knew that I wouldn't get any where but I had to try. Thanks again for all your support. My prayer for all of the mothers tomorrow is for a joyful, peaceful and blessed Mothers Day.
