It's a Younger Sister Thing
Having younger siblings is not easy. It's something that teaches you love, responsibility, and anger management. If you want to be a normal human in society and you have a younger sibling, that is automatically an impossible task. There's no recovering from that childhood trauma.
Look at what she did. And this is just a tiny piece of everything they make you go through as an older sibling. If you don't react in any way, you are to be respected, appreciated, and congratulated. Well done! You just beat the system.
