(A pair that looks like a man and a woman entered, they are siblings. K is the older brother, D is the younger sister)

K: "Good—"
D: "Kesha, look! A gay couple dancing! And there's a snowman chugging wine and becoming a snow cone. . . And. . . And. . ."
K: "Diana, to put it kindly, have it occurred to you why nobody invites you to a party?"
D: "Because I always get the dress code wrong?"
K: "It isn't. You always get everything wrong. And my name is not 'Kesha.'"
D: (slow realization) "Oh. . . Oh! Sorry!" (looks around and bows) "Good evening all! We are very honored to receive your kind invitation! I just happened to make a classic blackforest for you to enjoy! My brother tried his best to look for kirschwasser, he looked so distraught when I said pineapple brandy is the closest thing I could get. Also, I used. . . (cake rambling)"
(The siblings are putting the food they bring into the table)
D: (while arranging the table) "Okay, our new year is going to be sweet! Oh! Also, my brother brings his own wine in case the one here is horrible. He said the parties he has been to served shitty wi—"
K: (almost losing his patience) "This is a festive event, it is natural for me to want the best for everyone! What kind of rude guest am I to keep the finest wine for myself?" (tone became gentler) "I bring plenty of bottles to share! Not only wine, but some beers if it was to your liking." (looked at Diana) And since you are so nice to brought it up in front of everyone, it would be perfect for you to help me, so everyone can enjoy their drink"
D: ". . . Okay. . ."
(After finishing the preparation, the siblings greet the host, then start to look around and mingle)
D: "Kesha, Kesha! Look what I found in the corner!" (points at Jeffrey) "He looks so cute with the pathetic expression! Can I bring him home for a day and give him warm choco and biscuits? I will bathe him and put him in a cute outfit, too! Can I?"
K: "You can't. What did we agree about bringing a random human—"
(Diana has already rushed towards Jeffrey)
K: (Appears grumbling as he gave up on preventing his sister to approach Jeffrey, is actually curious on what will unfold)
I am sorry, they are mean. Though one is more like unintentionally mean and another is mean mean.
Also forgive some errors, I haven't written anything in a long time.
