In an ideal world, our siblings would only marry amazing people we get along with. But in reality, relationships with in-laws can be complicated and feel way worse when we feel like our sibling threw us under the bus.
Figuring out the line between calling out a sibling's spouse, and letting things slide can be deeply awkward, particularly in a public setting.
AITA for embarrassing my BIL after he told people I was their au pair?
Hi. My (22f) sister's husband had a "formal" work party where they were supposed to bring their families. As soon as we got there the host came to greet us, and she told me that "the other girls are in the backward". I see women around my age separated from the party with a lot of children and realized they were the babysitters/au pairs. I didn't mind and went there since I was there to take care of the children anyways.
