So my class at the time was an auditorium-like setup in the way that there were rows of seats instead of desks. With that in mind, one must be aware that if you're going to sit at the very edge of these rows, people are going to have to pass by the very narrow and inconvenient path you just made in order to get to their seat. Anyway, I got to class a little before it started so there was still plenty of seating available, yet this girl still chose to sit at the very edge of the row I typically sit in the middle of. She was digging through her backpack when I got her attention and asked if I could pass through, which was apparently a huge inconvenience to her as she sighed when she got up. Unbeknownst to me, she left her smoothie on the very skinny railing between the seats which my backpack doinked off and spilled all over the floor. Her over-dramatic reaction and refusal to even acknowledge me frustrated me in turn so I shrugged instead of apologizing. However, I did help clean it up. Once her other friends got there, she whispered to them while eyeing me and they all got up and moved, making me feel like some sort of social moron. Am I in the wrong here? It was a simple mistake and I didn't think I deserved the public shaming that I got. Plus the room smelled like strawberries afterwards. They're welcome.
