Input:  

This happened in my second semester in university, Majoring in chemical engineering. I had a chemistry lecture with assigned seats (this will be important later).

Me being the lazy dipshit I am I overslept and running late to my lecture, managed to get in there only 5 minutes late and luckily my seat is right next to the door so I didn't have to disrupt the class in a middle of a lecture. I see three of my classmates sitting in their assigned seat and greet me quietly as usual. I say hello back, and as I go to my seat I notice someone else's bag and laptop on my seat. I know this is one of the assistant teacher's belongings as I asked her questions sometimes mid-lecture.

I did not want to touch her stuff at first, I waited patiently until she can come back and pick up her stuff so I can sit down in my assigned seat. I was standing in a passageway where the assistant teachers can go and help the students in the rows further back. I was being a nuisance and one of the assistant teachers sitting at a desk in front of me noticed. She calls me over to tell me to sit in my assigned seat, I explained the situation and she told me to move the stuff to her then. I was hesitant and told her I don't want to touch other people's stuff as it could be rude. She tells me she's a friend so she wouldn't mind if I have her permission.

So I go back to my seat pick up the stuff carefully and place it in the desk in front of me where the other assistant teacher was seated. Went back to my seat and continued jotting down notes and asking questions per usual. Only 3 minutes go by and the owner of the bags and laptop sits directly behind me (That seat was is also taken, the student was probably at a restroom break or something or else I would've just sat there). And she leans over uncomfortably close to my ear and says along the lines of "Don't you dare touch my fucking shit again without my permission"

I went full PANIC MODE, I was stuttering my apology and tried to explain the situation as fast as possible before she freaking yells at me or something. I almost shat my pants at that point, I'm not a really confrontational guy also really shy. This puts me in a really bad spot. She walks off still visibly pissed, and my classmates were shocked too saying she was overreacting.

I wanted to give her a proper apology later on, but I couldn't. Whenever I try to go up to her and apologize for what happened that day I again go full panic mode and just quickly walk off before she sees me.

Am I the asshole though? Should I have waited?
