I wish I could post this on FB. But I have to "keep the peace" and "be the bigger person". (WARNING: RANT/LANGUAGE)

Dear sister in-law,
Eat a dick. No really, just go home and choke on it. I'm (not) sorry that I didn't personally hunt you down to let you know what my vagina will be doing on Monday. The only time I've heard from you in the past two months is when you got offended by something I posted on FB. So how appropriate you find out my induction date on FB. How on EARTH could your fatass survive without some goddamn drama to bitch about? I told your parents last MONDAY, and waited until THURSDAY to post on FB, so even they didn't see fit to fucking tell you. Maybe there is a reason. I guess you'll just find out after the fact on fucking FB when he's born, because guess what? This is a personal moment between my husband and I, and I couldn't give two shits if my son ever meets you. I kind of hope he never does.
Sincerely,
Go eat a dick.
