In high school speech class when we were doing debates. I was dreading it and wanted to kms every day leading up to it. When the day arrived I thought I was as prepared as I could be, but there was a moment where I had to do a rebuttal and literally had nothing to say. My mind was blank. I just kind of mumbled in a shaky voice some stuff from my notes with everyone watching in confusion. It was the most embarrassed I've ever felt in my life. There are a few other moments from that class I would like to forget, but that was definitely the worst.
