Motherhood
I have friends who've been caught out with the "Oh, I want a baby and stopped taking the pill three months ago" thing.

At the risk of sounding judgemental, said women generally feel that not only are they entitled to have a baby but also entitled to raise said baby at the expense of the poor schmuck who has been conned into fathering it.

I agree with Resident's comments elsewhere to the effect that just because women have a womb does not entitle them to use it. Especially if they feel that they're entitled to live at someone else's expense afterward.

Frankly, such behaviour disgusts me beyond words.
