In addition to AXH, both of my son's in-laws are alcoholics...one of them is in prison for his 4th DUI and for disabling a breathalizer in his car. My son's wife put herself through college, mothered her younger brother, and is one of the most impressive young women you can imagine.
So, for my adorable granddaughter (age 2), I am the only reliable grandparent---stone-cold sober, conscientious, responsible, and dutiful to a fault.
Alcoholics or not, I simply will never understand how they can choose a toxic liquid over her.
