2. GOOD BYE: Christine explains that in Korean, there are different ways to say "goodbye" depending on who is leaving. When the host is saying goodbye to the guest, they use "Annyonghi-gaseyo" (formal) or "Jal-ga" (casual). When the guest is leaving and saying goodbye to the host, they use "Annyonghi-geseyo" (formal) or "Jal-it-sso" (casual).
3. THANK YOU: Christine teaches three different expressions for "thank you" in Korean. The formal ways are "K(G)amsahamnida" and "K(G)omapsumnida", and the casual way is "K(G)omawo".
