Unless we really don't want to go somewhere, it almost always hurts to be excluded.
That goes double when you're the only one who's being left out of an event and it goes triple when the ones doing it make it clear they're excluding you for a petty reason. But whether you're being left out for something you can't change or something you shouldn't have to, it's obviously hard for that not to affect your relationships with people you thought were your friends.
That's all bad enough, but one woman is now facing an arguably more frustrating situation because she has no idea why this keeps happening to her.
But based on how her in-laws reacted to a sly response she recently undertook, it's apparently for a reason they feel strongly about. And that has a number of people feeling very suspicious.
