Write a story ending the statement ''I had never felt so embarrassed in my life

Almost five years ago, I was in fifth grade. For the majority of the year, the desks had a specific arrangement, almost like an "E". And when my teacher would check work or our homework planners to see if a parent/legal guardian signed them, she would walk between some of the additional desks sideways. She had a curvy figure, so I had always feared that I would accidentally hit her bottom ever since the beginning of the school year. One morning, she was doing a homework planner check and walked around like normal. Then it happened. When she was done checking my planner, I turned around to put it back in my backpack. Not knowing she was behind me (no pun intended), my elbow hit her bottom. It was totally an accident and I apologized about it. I had never felt so embarrassed in my life.

Explanation:

This is a true story of mine, so I don't know if you'll be able to use it. If you want to, you can kind of change the storyline a bit. (For example, say you know someone who's done this or make up a character.)
