The Sibling Off Limits Theory

I AM STILL VERY ANGRY/DISAPPOINTED/BETRAYED/CHEATED ARGHH SLAMS DOOR PUNCHES WALL RIPS OUT POSTERS DAMNIT LA FOREVER THE LAST TO KNOW URGH NOt once but twice guys cmon CMONNN COME ON

Maybe it's just me but I find it weird if your sibling dates someone your age or issit just me? E.g your younger sibling is dating someone older than you Like how are you supposed to behave around whoever their dating?!?!?! I would elaborate more but it seems to me I'm the only one who thinks this way I need to do more research and gather more feedback and responses.

And I hope you two are happy mann don't need be discreet anymore la its kinda obvious AND EVEN THOUGH I ASKED YOU SO MANY TIMES YOU ALWAYS DENIED BUT ITS OKAYE I FORGIVE YOU (just like your sister LOL) hahaha but damnit la at least tell me next time
