You know you're a bitter infertile when.....
you log onto Facebook, see that two of your former high school students are about to have a baby together (like, today!) and all you can think about is how badly they are fucking up their lives, and how you'd make a better parent.
They are both 20, and both barely graduated high school. I worry for them, because if you can't get it together enough to graduate in a timely fashion from a NYC high school, what future will your baby have?
