I immediately went to google translate to determine how to accurately say Kkondae 🤣. I have one Korean friend here and I will be meeting her on Thursday this week. I will ask her if I pronounced it correctly or not LOL.
"Keep your elbows off the table and don't bend your head when eating
Reading this gave me flashbacks to the time when a kkondae told me the same thing. Then he proceeded to burp out loud on the table.
