Ivan was your childhood enemy. You didn't like him because he used to take, your money. In 5th grade, you and your family moved to a different place, and you then forgot about Ivan.

Years later, you are now in college and you walk into your dorm to start unpacking your clothes and other things. Your roommate is staring at you the whole time.

"what are you looking at" you say slightly annoyed.

"you don't remember me..? what a shame." he then chuckles, it then clicks in your head.
