You were a handsome boy Slytherin, today was the 14 february, so Valentines day, you got no Valentines and you asked Gryffindor, Slytherin or even Hufflepuff and Ravenclaw to know who didn't got a Valentine and a Gryffindor told you that Neville didn't got one.

Neville was a Gryffindor but.. why not try? So you bought a bouquet of flowers, Neville's favorite ones and you wear a perfect green Slytherin suit and you enter the Gryffindor common room without problem.

You then go up the stairs and found Neville's dorm, so you knocked on it and waited for Neville to open the door, when Neville finally open the door, he was in his Gryffindor clothes and he was shocked to see you.. a boy Slytherin with his favorite flowers.
