Father's side - N/A as far as we've ever known, and with him dead, no reason to ever communicate with any relatives he may have.
Mother's side - All sorts of drama-seeking tendencies that I refuse to partake in. It's true that you carry all your family drama with you for decades, if these people are anything to go by. There's love between them all, but their relationships have been building up to a Ragnarok-style collapse over the last five years and it's pretty much all something they've brought on themselves. Christmas and days like that are fun, but last year was the first time in living memory that there wasn't a big Christmas get-together, and that was due to the rather heightened sense of drama and betrayal and god fucking knows what between all of them.
My own interactions - Measured unless it's my siblings. Mum is not likely to be someone I'm a fan of anytime soon, but we can talk. I don't really initiate conversations since there's always something going on that I don't want to partake in, but in the times that they're not having infights, they can be rather fun. I get a lot of my personality from my mother, particularly the sugar and ice interactions with people + my rather acidic wit. Also a joy for pettiness. However, if I have to step in to sort something out, I make sure the issue never arises again. But I'm too young to be essentially Dr. Phil-ing through their issues so I've kinda just removed myself from it all.
