You're a 6th year Gryffindor and a Potter wandering the corridor and you saw Draco

Draco: Hey Rosie Rosie: Is something wrong? Draco: I wish I could have said this before, but I've fallen in love with you... Rosie:... Rosie: Do you get deja vu, huh?

Draco: Did you guys hear that little Potter has a crush on me!

Draco said sarcastically

Rosie: I really am an idiot
