Eh, I think it’s cute. Neither skeleton is gendered with bonetits or pink wraps or a tie and it doesn’t come off as hateful, it’s just observational humor about how different sleeping styles can cause friction.
That's kind of okay, isn't it? Sure not every woman is a sheet-steeler, but woman tend to be more cold than man and steeling the sheet when cold is more of an instict and less of an 'I hate my wife' vibe
