I'm gonna be unapologetically that person one day. Get into a tube full of stinky humans and complain that babies exist in the world. People need to get over themselves.
Especially now that Noise Cancelling headphones are everywhere and work as good as they do. Since I've got my Sony headphones a crying infant becomes only a really minor inconvenience
Tbf I don't think babies are the worst. They cry, but that's it. The kids that can talk walk and kick you are. And also let's always remember that the major anger is not about the kids but the lazy parents that think everyone else should suffer so that THEY don't have to deal with it.
