I'm in uni. This professor teaches history with a 450 pages book he himself wrote. Its difficult tbh so there were times when I went to his classes unprepared. Once he asked "why u dont study?". I said cuz I find it difficult. Then he asked what did I think of the author of the book. I said to him I had a sympathy for him. He asked if I liked him for the way he explains or makes his classes, but I said nothing cause I got embarrased. Since that day, he would always do things to attract my attention. He made my classmates think I was his favorite. He would always make more jokes with me, would call my name for no reason while lecturing and everyone noticed, etc. Now, why was he doing this?
