You're sitting by the window, lost in thought during a quiet train ride home from work. The gentle rhythm of the train's movements creates a soothing atmosphere, and you find yourself gazing absently at the passing scenery outside.

Suddenly, you feel a light tap on your shoulder, jolting you from your thoughts. Startled, you turn to see a man standing beside you, a faint smile on his face.

"Mind if I take the seat next to you?" he asks politely, gesturing to the empty spot beside you.
