I guess we all have a crazy SIL. We live in another state so a lot of the time I hear about things on FB from her before from my family get a chance to tell me.
She uses FB to vent her family issues and ends up having big arguments with them (only met them a few times but they seem as nuts as her) for everyone to see. Which is fine if that's her thing, but it drives me crazy when she vents about my brother and only tells half truths to make her look like the victim and my brother the badie.
Latest thing she did... boast about getting into a car accident and having bruised ribs. When I asked if the kids were ok she said they were at home being looked after by a neighbour. It soon came out she left them at home ALONE asleep (ages 9mths & 4yo!!!!!) but of course that little bit of info was left off FB. Would love to mention that on her FB page and see the response that got!
Sometimes better to be the bigger person and not get sucked into being like them, but geez it's tempting sometimes lol
