Annette to God:
Dear God, my adorable brother M. just wrote me and asked that I say hello to brother P. and his wife and tell them everyone sends their love. That seems a very normal thing to do, but You know how wary I am of speaking to brother P. in person or saying anything that might lead to him and his wife visiting our parents in Florida and maybe unconsciously hurting them. You know what I mean, God.
P. and his wife probably don't mean to hurt anybody, but they have so much unconscious rage, or whatever, towards our parents and brother M., and it may not be a good thing for them to interact with the family.
What do You say about this, God?
God to Annette:
I say to My loving daughter, if your brother M. wants to say hello to his brother and his brother's wife, is he not capable of doing that himself, wherever he may live? Why are you an intermediary? Why does he give you that role, and why do you accept it?
In a case like this, there is a lot of drama, as you point out. If there were different relationships here, it could be perfectly ordinary for M. to say to you: Give P. and his wife a hug for me, or some such. After all, you and P. live in the same town, and M. is far away. But the relationships here are muddied.
Obviously, M. would like there to be something better between him and his brother and his brother's wife. But that is up to him and not to you. In the same way, if you decide to make overtures to P. and his wife, it is up to you. You can elect to, or you can elect to leave it alone.
M. can take care of himself.
You feel protective of your parents, but it is not for you to concern yourself with what M. and P. do or don't do. If P. wants contact with your parents, that is up to P. and his parents. It is not up to you. Be not an intermediary nor use intermediaries.
You are not responsible for what others do, My dear Annette. You are not a guardian of the world. Leave others to Me, will you?
