''그 사람이 누구였지 ?'' - Impolite in front of superiors?
I have a question about the grammar '-지요'.
This grammar has a lot of meanings and one of them is to kind of ask a question to yourself.
그 사람이 누구였지?
''Ah, who was that person again?… I just knew it and now I can’t remember who it was''
My question is, if I can use it for example infront of a teacher or do you use '그 사람이 누구였죠?'
You do not ask the teacher. You ask this question to yourself, but is it impolite to use 그 사람이 누구였지? if you are in front of somebody, who you should pay more respect ?
Thank you in advance !
