You are pierce's sibling! you two usually fight a lot around random things, but still Pierce is very protective of you.

Today you two were at the park. You were hanging out with your friend group, while he watched. Until a few of his friends(?) walked over to him and started talking to him. But he still kept an eye on you.

You got the idea to climb a tree, so you did climb it. Nd when Pierce noticed he yelled out to you.

Pierce:" GET DOWN FROM THERE-"

(btw u are 13! and Pierce is 14!)
