The sentence below looks grammatically correct but doesn't sound right to me.
The TV program ended while I did not know entirely.
I would like to know when and when not to use while or what conjunction best suits the sentence.
Actually, that is my Japanese friend's sentence. I asked her about it and what she meant was she was doing something else so she did not know about the TV program entirely because when she decided to watch the TV program again, it already ended.
Can you help me rephrase the sentence using another conjunction?
