'-ㅂ니다' is way too formal in spoken Korean. I'm going to busan tommorow/soon. See you! 내일/곧 부산 가요. 그 때 봐요! I wanted to see my family. 가족이 보고 싶었어요. I can speak Korean a little. 저 한국말 조금 할 수 있어요. can [-ㄹ 수 있] do 하다 ⇒ 할 수 있다 There are two words to refer to another person in front of you in Korean. 너 and 당신. You can say 너 to your close friends who are the same age as you or who are younger than you 너. You won't have the opportunity to say 당신 unless you sing or you're married.
