I’ve discovered that people in Korean are particular about their footwear. There are shoes for the shower, shoes for the outdoors, and slippers for indoors. When I get to school I take off my “outdoor” shoes and exchange them for a pair of slippers. I’m borrowing a pair from the school until I purchase my own.
Even though I’m in normal clothes, the slippers make it feel like I’m in pajamas all day. And I don’t hate it.
