Why Do People Stare at Strangers on the Subway?

People stare at strangers on the subway because it’s a quiet moment when they feel noticed. It's like when you’re sitting in class and someone looks at you, you might wonder why. On the subway, people are often tired or stressed from their day, so staring becomes a small way to connect. Sometimes people just want to see if another person is also looking back, it’s kind of fun! In some cases, they may even smile or give a little nod, like saying hello without words.
