So we just had a quiz and I ask asking him some answers and he gave it freely. Minutes passed I saw him trying to say something to me but I cant quite understand what he was trying to sat so I assumed he was asking if I got the answer right, so I just kept smiling and nodding at him. The quiz finished and as I approached him he was so mad at me because he didnt get any answers from me. I told him  "I thought you didnt need any" and he said that time where I just smiled and nodded, he was actually asking for some answers.

I feel bad for not sharing the answer and might cause them to fail the subject. AITA?
