Guns Aren't The Only Things That Need Safety's

Sorry for the delay, folks.  Abby felt that people on the verge of suicide and teen runaways weren't as important as old people going to see an ophthalmologist.
Here you go:

DEAR JERKASS: My 19-year-old son has been dating the daughter of one of my friends I'll call "Mona." We didn't set them up; they met at some parties. Last summer we discovered they were having sex because "Meghan" thought she was pregnant. Luckily, it turned out she wasn't. They broke up but have gotten back together recently.

When I asked Mona if she was putting Meghan on birth control, Mona said that she wouldn't because "that would be letting her know it's OK to have sex." I said, "Better safe than sorry!" and we left it at that.

I let my son use my car last weekend and found an opened box of emergency contraception on the floor. Because my son never answers his phone, I called Meghan and stressed to her that unprotected sex is irresponsible and that they aren't ready for a baby. I warned her to take precautions and get on birth control, and I helped her to make the arrangements.

Was it wrong to discuss this behind her mother's back? Should I tell Mona after promising Meghan I wouldn't say anything? What should I do? -- MOM VERSUS FRIEND

DEAR OSTRICH,
19 and you're just now having "the talk"?
You ignorant moron.
And yes, it was wrong to talk to his girlfriend without talking to him first, even if he "never picks up the phone".  You should have raised him to be an adult BEFORE he turned voting age.
While the content of what you said was correct, how you went around it was wrong.
Now we have a coddled man-child who's mother is going to involve herself in his sexual activities.
And no, you shouldn't tell "Mona" because that woman already has her head up her ass, as well as the fact that Meghan's not your daughter (yet, who knows), and you may end up causing another break up as well as resentment from her.
What's done is done.  Instead of writing an advice column you should have gone to some parenting courses.
