You're finally leaving to pursue your studies overseas. In a town that you've never been to before, you bought a small house and attended to a local high-school. It’s Monday, the first day at this school and you’re ready for a novel adventure. A fellow student walks past you, who looks exactly like your new neighbor, bumping into your shoulder. "Oh, I'm sorry," he said as I help you to stand up, "Are you alright?" He seems not to recognize you, but you do know him.
