Ok, just telling some stories now.... Once BM freaked out once because one of the little guys dressed himself and didn't put on underoos. We laid out the underpants, but little guy decided to go commando. This little guy is six, so he uses the potty by himself, we did not check to make sure he was wearing undies all day, but when we dropped him off BM found out and acted like we had committed some kind of child abuse! More recently DH bough the kids halloween tshirts from wal mart that said "zombies eat brains, don't worry, you're safe!" And BM screamed and screamed about how offensive they were and how she couldn't send them to school in those shirts and how if they wore them at school they'd be sent home! First of all, they were kids shirts for a buck a piece, for HALLOWEEN! Second of all, we only have a handful of clothes for the boys, because they live with her. We send them home in clothes, she sends them back for a weekend wearing pajamas and socks, so we have to buy clothes, outerwear and shoes every freaking time, but we have a growing pile of pj's the boys are outgrowing. She freaked out once because we brought one of the guys back in a pj shirt, even though it was an ordinary t-shirt, apparently because it had originally come with pjs it was "inappropriate".
Once BM got insanely furiously angry that DH didn't tell her that his elderly cat died. She did not want the cat, she didn't ever want to know about the cat, she never asked about the cat. But the kids came for a weekend, asked about the old cat who was missing, and we had a gentle convo about how he had been sick and was in kitty heaven now. Kids took it just fine (he wasn't a beloved cat to them, they were afraid of the old geezer, he'd hiss at them!). BM freaked out for days. Not even about how we explained death or anything, just that we hadn't TOLD HER FIRST WHEN WE PUT THE DAMN CAT DOWN.
Oh, she recently got frothing mad and called DH and then called me because she was stalking me on facebook and i had made a vaguely insulting reference to someone who was bothering me (it wasn't BM, i have a strict no BM mentions policy on my FB). She of course assumed the reference was about her, despite no names or anything remotely to do with her or the kids in the post or comments. But instead of admitting she had been cyberstalking me, she made up a story about how one of the kids told her i called her this name. Which is funny, because the only person i use this name for is absolutely not BM, and when she said it, i knew right away where she had found it! She is and always has been blocked on FB, but she apparently logged in with someone else's account to find me, despite my having my fb on friends only. I have since edited my friends list very extensively.
Oh, she got outrageously angry that DH allowed SS6 and SS8 to watch Doctor Who. We let them watch the christmas show with the flying sharks. The kids adore sharks. She has never seen Doctor Who, and has no idea how scary it is or isn't. We would never let them see certain scary episodes, but we had vetted this one. The kids were not disturbed or scared by it at all, but BM was through the roof. She has also attempted to ban us from letting the kids watch the ANIMATED BATMAN CARTOON SHOW. Extra nutso is that both kids have seen every episode already, and love batman more than they love Santa, i think.

Tell me your stories! Weirdest most irrational freakout!
