Have you heard the one about the 13-year-old who knocked up the 15-year-old? No? That's because it's not a joke.
No, the joke is that everybody involved agreed to keep it secret until the girl's mother noticed the bulge. Yes, the boy's family helped keep it secret. Heck, the boy's dad is proud of his son. Quite a chip off the old block.
I could segue here into knocking the U.K. welfare system, talk about how it actually rewards this kind of behavior and all that, but I won't. Suffice it to say that if this happened to my daughter, I wouldn't be talking about how great a mother she's going to make.
