"The session that we attended day before yesterday or Monday session."
"The session that we attended the day before yesterday." Even with my correction, this is not a complete sentence. Please write another.
"Did you attend the Monday session?" :tick:
See above.
Did you really manage to miss the correction I made in bold and red in post #8? Please add the missing word and use the correct punctuation mark at the end of a question.
"Do you remember, the session that we attended the day before yesterday?"
