Political correctness has reached the level of absurdity. Recently Fio read that former politico John Edwards "fathered a child WITH his mistress," a physical impossibility and an incorrect idiom. First, it's impossible for a child to have two biological fathers, especially if one of them is a female. Second, a man fathers a child ON his mistress not WITH her.
Which reminds Fio, she often reads or hears of a husband announcing that he and his wife are pregnant. Nice try, guy, but unless you're Schwartzeneggar or trans-gender, that's impossible. SHE is the one who is pregnant. You merely, uhm, fathered the child.
