Why did my Korean friend suddenly switch to 존댓말? How to read the polite-speech plot twist

반말
When is it OK to speak 반말? The unwritten rules of dropping formality
Who gets to say 'let's drop the formal speech', why same-age friends switch in seconds, why ordering coffee in 반말 is a small act of 갑질, why a sudden return to polite speech is a cold signal, and how Korea's offices are rewriting the rules.

Why Koreans rarely say 'no' directly (and how to hear it anyway)

단톡방
Your first Korean group chat: KakaoTalk read receipts, reactions and the art of silence
How the KakaoTalk 단톡방 works: the unread '1', 읽씹 vs 안읽씹, ㅋㅋㅋ vs ㅎㅎ, paid emoticons, work chats after hours and the right-to-disconnect debate, family good-morning images, reactions, leaving quietly and the polite habits that keep you out of trouble.
팔짱 끼기
Why Korean friends hold hands and link arms (and why it isn't romantic)
Female friends arm in arm, male friends draped over each other's shoulders, mothers and daughters holding hands: what Korean friendship touch means, why it surprises Westerners, why your hug might surprise Koreans, and how it's changing.
언제 밥 한번 먹자
'Let's grab a meal sometime': is a Korean invitation real?
언제 밥 한번 먹자 is the most famous friendly lie in Korea. How to tell a warm goodbye from a real invitation, what a 집들이 housewarming involves (and why people bring toilet paper), and how to turn 'sometime' into an actual date.
