What would you do if your little brother said fuck you?

Let's say you have a 13 year old brother. He's kind, nosy, and you play with him/ talk to him daily. One day he finds out you are going to college out of state. He says you should stay home with me but you say no.
He SCREAMS, throws his plate of food on the floor and says fuck you! FUCK YOU! he runs upstairs and starts trashing your room. He even throws your laptop across the room and destroys it. He says he hates you, your the worse brother/ sister ever and he doesn't care that your leaving. - what would you do?
