It doesn’t have to be. It’s just something that most often falls to women due to our current culture.

The link explains in more detail.

The comic is basically "women have harder lives when they have low standards for the man they let knock them up."

I can't imagine walking into a kitchen then blaming my wife because of a pot of spaghetti overflowed, especially when she was busy dealing with two kids AND had her friends over. Or expect her to make dinner for me, the kids, and her friends all by herself.

I also can't imagine any of the men I know would do that...which the comic describes as a 'common scenario for many parents'.

That sounds like a low quality partner issue, not a gender role issue.

What strikes me about the comic is that the guest is talking to the husband, while she's there for the wife. It would make a lot more sense in this situation if the husband took care of the kids while the wife took care of her guest.
