Well, to continue the stories of interesting family, may I present a branch of my family?
Background:
Uncle & Aunt have 2 boys, one factors in, we'll call him Cousin.
Cousin married Girl.
Uncle & Dad are brothers
Sister and Boyfriend (BF).
Everyone is white (extremely), except Girl is Chinese and BF is Indian. (this is relevant)
So, Uncle & aunt haven't been decent human beings to Dad, and by extension, me and Sister, at least until we got older and had the potential of adding babies to the family. As a result, we don't really have a relationship with Uncle & aunt, and don't particularly want one. We avoid them in general.
Cousin & wife invited Sister and BF to dinner. They went to dinner, and discovered that Uncle and Aunt were also there! This had not been mentioned ever. Dinner/evening went ok per Sister, slightly awkward, but 4 year old twins really help smooth everything out.
The next day, Uncle does a group text which does not include Sister and BF. In text is a group picture from the evening. Caption: "Guess who's coming to dinner"
Given general ages and history of this guy's behavior, it's pretty safe to assume he was referencing the movie. (Google "guess who's coming to dinner" if you haven't seen it) Ugh.
