I had a fight with my professor

Hello everyone, today I am going to share one of the most terrible incidents of my life. Actually once upon a time in my college, I had a fight with my business professor. The fight does not mean here physically just by conversation. That day I forgot to take my notebook to college and he asked for my notes. So I said very leniently that sir I forgot to bring it for today and I will show you by tomorrow. Then he just slapped me in front of the class without any reason. So I shout there and disrespected him in front of the whole class. Then after we had a long conversation and at last I just left the class and came outside. That day was not a good day for me and really I always feel sad for that day. Guys, please tell by commenting on mu post that did it was the right action taken by me or wrong?
