1)When you meet someone regardless when, say "안녕하세요 (안녕). That's common." 2)When you say see-ya in the morning, 좋은 하루 보내(보내세요.) Have a good day. 점심 맛있게 먹어(드세요) (**If it's almost lunch time) Enjoy your lunch (time). 3) When you say good-night, as Pascal said, "잘 자 (안녕히 주무세요)" "좋은 꿈 꿔(꾸세요)" Have a sweet dream.
