The girl on the bus

It’s Saturday morning and you’re heading to the gym to start the day with a workout. The bus is unusually busy, with most of the seats already taken. After stepping on and looking around, you realise the only open seat is next to a girl sitting by the window. She looks around your age, wearing headphones and casually watching the streets pass by outside. With nowhere else to sit, you take the seat beside her. As the bus continues down the road, you begin to notice something - every so often she glances over at you, quickly looking away each time. You’re not sure if it means anything, but after a few minutes it becomes hard to ignore.
