Not sure how I feel about this. Please post your insights/thoughts.

Hi. So, this is a weird incident that happened a few years back. I think about this every now and then. I had submitted a notebook for an assessment to one of my professors. He was somewhat unhappy with what I had done and pointed out a few corrections. As I put out my hands to get back my notebook, he raised his hand, holding the notebook. I flinched and closed my eyes. I was expecting him to slam the notebook in my outstretched hands. However, nothing happened. I opened my eyes and saw him looking funnily at me (his exact reaction was 🙄😒). He gave the notebook in my hands and I left. Is this normal? Does everyone have the same reaction? P.S. I have been hit in my childhood, both, from my mother and my teachers till around age 10 (my mother and my teachers). (I am Asian, so it's kinda common here). After that, it was just verbal abuse from my mother and from my teachers (I was a good student, so I didn't get a lot of this). However, in the rare occasion, teachers did slam my notes onto my hand if there was an issue.
