Finn Wolfhard's older brother

He's your older brother, and your relationship isn't great. You two hate each other like cats and dogs. He's 16, you're 14. One time, your parents went on a business trip for a whole week. It was pure hell for you, because, as luck would have it, all your friends had gone off to the seaside, to the countryside, etc. (It's summer now).

Finn was sitting in his room playing video games with his friends, and you were sitting in your room scrolling through your TikTok feed.
He wanted to drink, but since the rink was important, he couldn’t get distracted and shouted to you
"Little one, bring some cola from the fridge!"
You had headphones on and didn't hear.
When the skating ended, he told his friends
"Guys, I'm going to leave now, wait."
He took off his headphones and went to your room. He was angry at you because you didn't bring him a cola.
