These come from suggestions by Usual John and Jack Applin, both of whom call the 12 December one a cry for help!
From 5 December
From 12 December
Note that, the way the Six Chix rotation works, two comics a week apart will be by the same artist – in this case Bianca Xunise.
Is there a way to interpret these that isn’t dark?
P.S. And on another Tuesday….
From 19 December
From 26 December
Comics I Don't Understand 
The interpretation is that Tuesday Chick has never, ever been funny. Not once. And she intends to continue being anti-funny as long as she has the gig.
That seems unnecessarily harsh, beckoningchasm. But I was going to ask if anyone had checked on her to make sure she’s okay?
Six Chix is never funny or understandable. And this Tuesday chic is taking up space.
Let me copy-paste a reminder of the first item in the CIDU FAQ page:
I don’t think any of the comments so far have gone over the line, but everybody please keep in mind the idea of restraint even while you are free to register your dissatisfaction with some strip or feature.
Yours sincerely,
The Tone Police
(And why has “tone policing” become such a no-no on political social media?)
For the curious, here was the next Tuesday panel:
Setting aside whether it’s funny, I understand the last three; as my daughter would explain “Oh mood!” The first one started as a CIDU. I think is a cat owner & cat hiding under the bed covers because they just couldn’t face the day. … another version of “Oh mood!”
Chipper42: I like that interpretation much better than mine, which would get the person arrested in most places.
Very Seasonal Affective Disorder-y strips.
The cliche is that childhood is a time of delight and wonder and all that stuff. Charles Schulz got beaucoup mileage out of fears, insecurities, aggression, frustration and loneliness in childhood. But he also knew his way around a story arc.
@ Daniel (9) – As Bill Watterson wrote about “Peanuts” in “The Calvin and Hobbes Tenth Anniversary Book” (page 17):
“… I’m amazed at what a melancholy comic strip it was in the ‘60s. Surely no other strip has presented a world so relentlessly cruel and heartless. Charlie Brown’s self-torture in the face of constant failure is funny in a bitter, hopelessly sad way. I think the most important thing I learned from Peanuts is that a comic strip can have an emotional edge to it and that it can talk about the big issues of life in a sensitive and perceptive way.”
Speaking of melancholy Charlie Brown, have you ever really listened to the song “Christmas Time is Here” from “A Charlie Brown Christmas”? I heard an instrumental version at the supermarket and was struck by what a sad-sounding song it is. When you add the words you can just imagine it as the background for a severely-depressed lonely apartment dweller, looking out the window and watching the children at the park, and then looking at the pictures on the wall of his dead parents and the wife he lost to leukemia, and then looking out the window again, and finally going into the bathroom to find a razor blade or a whole bottle of blood-pressure pills.
I think the best way to look at Bianca’s strips is that they are observational, and not really intended to be funny. (Political cartoons are also generally not intended to be funny.)
But it’s hard not to hope her personal life is more cheerful.
Sure the overall tone of the Christmas special is not the super-cheerful holiday happiness of other Christmas shows. That’s what made the Special, well, special. Growing up is complicated, and so are the holidays. :-) (Note that while ol’ Chuck may have had his bouts of melancholy, he was still a well-rounded 20th Century boy).
The Latin jazz soundtrack also makes the Special stand out. The resulting record album was a hot seller for some time.
(Skip to around the 6-min mark to address the Christmas Special though the entire video is a fun watch.)
There also are technical tutorials on “Christmas Time Is Here” on YT that explain the chord changes, if one is musically inclined.
I also meant to mention that the comics at the start of this thread might make good T shirt graphics.
