Someone has outgrown his shoes, or rather, his shoebox.
He stubbornly stuffs himself in his box, no matter how uncomfortable.
Too bad there isn't a belt attached that he can loosen in order breathe more easily.
Luckily for him, Christmas is just around the corner.
I would suspect that Santa will be bringing boxes of all shapes and sizes.
Hopefully, there'll be one that fits him just perfectly.
