A little humiliation

Reluctantly, I walked forward barefoot. "Hmm, no shoes Amira?" the teacher asked. "No answer sir." "Ok whatever you want Amira. I would like you to solve the circulatory problem with a clear explanation of why you are doing certain steps." Nervously, I began to stammer a little and wanted to write some things on the board. But what happens? I dropped the marker. Picking it up with my short dress would bring a whole lot of attention that I didn't want, but yes no choice.

Carefully I tried to sink through my knees to pick up the marker, but I lost my balance and fell forward on my knees. The hem of my dress blew up and my bare bottom became visible to my classmates and worse, my teacher. Red with embarrassment, I tried to get up and wanted to continue with my solution but the teacher stopped me.
