I am hearing stories now about XW. "People are calling her the f-hole of Anywhere, NY." "She was doing jello shots off of John's stomach" (the husband of my son's den mother). "She was sucking face with some guy for over an hour in the corner of a party."
Sounds like her few remaining moral standards are deteriorating rapidly. I would not be surprised if she does not contract some serious STD in a short amount of time.
You, on the other hand, are quite aware of what your kids are going through and are their stable rock.
