Dean and Seamus sharing clothes without even noticing. Everyone saying stuff like “wait, isn’t that Dean’s shirt?” and them just being all “is it????” Snape making really snide comments in class and them not getting it at all because wait?? This is Seamus’ tie? It was in my bed though. Huh. Their moms being all OMFG THATS WHERE THAT COAT WENT?? THAT T-SHIRT?? THESE TROUSERS??? OH MY GOD NO WONDER HIS SOCKS ARE TWO SIZES TOO BIG FOR HIM. UGH.
