I have three younger sisters and will soon have a younger brother. The oldest out of my younger siblings is cool, the youngest is 1 year old and kinda just runs around randomly, but the middle one? She's annoying. She constantly interrupts me. She jumps in my bed without permission, even though when I go anywhere near HER stuff she yells at me as if I'd broken it even though I literally brushed it accidentally. Also, no joke, she sometimes even treats me like I'm her 5 year old daughter. She says things like "HOW MANY TIMES DO I HAVE TO TELL YOU (insert thing here)". And, a pretty funny scenario:
The oldest of my younger sisters helped me simply by passing me a spoon juring breakfast, and ther annoying one proceeded to say "DON'T DO THAT SHE WILL NEVER LEARN TO DO IT HERSELF"
1: Jeez it's just a little bit of kind help
2: You're like 4 and a half years younger than me
3: It's litterally getting a spoon.
