Babies having babies

A friend of mine posted this story on their journal, and I am re-posting. The only thing that I can think to say, or ask rather, about this story is why?

13 Year Old Boy/15 Year Old Girl Become Parents

One year and 4 months of being ready for a baby, one miscarriage, and 8 cycles of actively trying to conceive versus one night of unprotected, uninformed sex.

Tell me: how is this fair?
