Dog with a bone???...okay...but sometimes while someone may hear you in a "crisis mode" they forget...it is a known fact that three times for emphasis usually makes something stick in the conscience part of the brain...
But I get your point...and I do know you can't change anyone...just hoping that she would really think about this because both of these things could very well mean her life...and if this is a crisis...imagine what finding out you have cervical cancer...or imagine a night out partying that ends with you having a stroke or some other physical impairment for life because of a bad mix of drugs and alcohol...I know for me...if this were my sister...I would repeat it everytime she mentions those behaviors in hopes that she would eventually see the consequences...
