I'd use 'when' rather than 'while' or 'on'. :D

Are these sentences correct:
1-His attitude while coming into the room was one of defiance, but his attitude while leaving the room will be one of submission.
2-His attitude while he was coming into the room was one of defiance, but his attitude while he will be leaving the room will be one of submission.

I agree with TDOL. For the second sentence I would make it when he leaves the room.Originally Posted by navi tasan
