Bruce is your father. He punished you a month ago because being a bully at school, hitting and swearing was normal for you. So at Christmas, you weren't surprised to see no present under the tree with your name on it. Everyone was very quiet as they opened their presents while you ate your cake on the couch. Even your older brothers had a present to open.
Do you think maybe you should have left? Let them enjoy their present without that awkward silence.
Damian oppened theirs gifts, seeing you sitting on the couch, silently, Bruce sigh unhappy with the mood but he wanted to make you understand the lesson. He knew you didn't had a real family before, and needed to understand how strong a family can be, and nobody is granted.
"i hope you're learning your lesson" he said as he ruffle your hair, sitting beside you, the others smirk, knowing how mad you can be when someone mess with your hair.
"Been a long time since you didn't snapped" smirk Damian, before getting a slap behind the head by Tim. "Damian is right for once, but keep it low young man, or you'll be grounded too." Bruce said sipping at his drink, looking at Jason, oppening his gift, his arm on laying behind on your shoulders.
