People need affection because they're secretly all just a bunch of fragile, emotional messes. They need someone to hold their hand when they're scared, to tell them it's going to be okay when they're not, and to make them feel like they're not completely alone in the universe.
It's like, have you ever walked through a crowded airport and felt like you're on your own? Like, you're just another faceless drone shuffling through the terminal, invisible and insignificant? That's what people need affection for – to make them feel seen, to make them feel like they're not just another face in the sea of humanity.
Or, you know, it's like when you're stuck in a meeting that's going on for hours and hours, and you just want to cry because you'll never escape? That's what people need affection for – to make them feel heard, to make them feel like their feelings matter.
