Kids these days (Yes, I said that unironically) can’t be assed to deal with any amount of discomfort. They’ve had a childhood of screens put in front of them so they don’t have to deal with boredom and other shit that just ruins a person’s ability to operate in society.
Grow the fuck up and deal with it.
EDIT: So apparently people are reading this like I’m talking about the crying babies. I’m talking about the ridiculous, pseudo-child-free adults who can’t believe a baby might have trouble while flying and god forbid they should hear it cry.
