DEAR ABBY: My 13-year-old daughter, "Dena," is in the same grade as her friend "Amanda." Amanda has a sister, "Barb," who turned 15 last month. Amanda told my Dena that Barb's 16-year-old boyfriend has been sneaking in Barb's bedroom window several nights a week for a while now, after their mother and stepfather have gone to bed. Amanda also confided that Barb told her that she and the boyfriend have had sex a couple of times, including before Barb turned 15.
I am not close to the mother and stepfather, although I do run into them at school functions. I wouldn't begin to know how to approach the parents and tell them what I know. Should I be concerned with what's happening in other people's homes after they've gone to bed? Or should I keep this to myself and let them find out the hard way down the road? -- ANOTHER MOTHER IN OKLAHOMA
DEAR MOTHER: Do unto others as you would have them do unto you. Call that girl's mother and tell her what you know and how you learned it. If what your daughter's friend confided is true, they need bars on the windows and a chastity belt for Barb (and some serious counseling).
