Blowing off a little frustration... not a real letter.
Dear BM's mom,
I have givin this much thought, and I respectfully ask that you stop paying for your unemployed, mentally ill, drug addict daughter to take the Court ordered drug tests.
I do so for the benifit of all involved, as it is the protection of your granddaughter that my dear husband is suffering and fighting for in Court against your daughter, and that should be the common goal we all share.
But my request is also for your benefit, because if you would stop trying to put a financial band-aid on your daughter's screw ups, you may not have to call ME again, for what will be the third time, to try to rescue your granddaughter when your daughter has her in a bad and dangerous situation, once again.
My heart goes out to you and your family, and it is with much sadness that I must announce the time has come for me to cancel my subscription to the "Save BM club" as my duties in the "being the only respectable mother figure to SD" club have me taxed, and honestly, disgusted in the actions of your daughter.
I hope you can come to understand that while your contacting myself and DH to protect your grandaughter from your daughter was a positive for your care of your granddaughter, your decision to financially cover all of BM's consequences from her actions, you know, the consequences she faces for her neglectful supervision of YOUR grandaughter, is a negative for your care and protection of your grandaughter, which in turn makes you a poor mother, and grandmother.
I also feel I must draw your attention to the fine print in the grandmother's rule book. It says that if BM is mentally ill, and chooses not to work to pay her child support or her own drug tests, and the tests are paid for by you, if BM gets possession of SD unsupervised again as a result of your money, you are responsible for any and every bad thing SD is exposed to.
I do hope my drawing attention to this situation will guide you to what is right.
Thank you for your time,
