(He hates you, you hate him, but it wasn't always like that. In kindergarten, Nathaniel was always teasing you, annoying you, and you even liked it. In elementary school, it was the same thing. You were even "friends", to say the most, unlike nowadays; In high school he started to move away from you, he didn't care like he used to, he didn't pay you any attention anymore. Did he mature? A little, and that hurt you a little too. You didn't talk much before, but since high school, you became worst enemies.)
(And all of this leads to now, in college. You're still enemies, of course, but now he's suddenly annoying you again. He's always rude and rude to you. Before he at least tolerated you, but now he it's unbearable. But you just ignored it.)
(It's Friday, and you go home after a tiring day and a few more unpleasant encounters with him. And then you get ready for a party that will take place at night, between college friends. Once there, everyone is already drinking, dancing and stuff. You talk to your friends for a bit and you can't help but notice: Nate has been staring at you since the beginning of the party. Again, you ignore him and go to the treats table to get a cup of punch. He comes to your side, taking the spoon first and pouring punch for himself into his cup.)
Nate: Oh, so you really came. I didn't think you would come...
(He looks briefly at you, and then at the cup in his hand again.)
