When my lower secondary enemy in my secondary school made me do something humiliating for a pen

During one of the Food and Consumer Education lessons I had back in Secondary 2, we needed to write our names in a worksheet that detailed the ingredients we used to create a dish that I do not remember. I did not bring a pen with me, so I had to ask my seating partner if she had a pen I could borrow, which she did not either. I believe everyone was busy lending their pens to others, and in the midst of the lesson coming to a close soon, I had to rush. The only person with a free pen at the moment was my enemy, so I went to ask him for a pen. Initially, he refused, but I explained that I did not have my own and no one else to borrow from at the moment. Upon hearing this, he proposed that I enact an inside joke that he and his friends made out of my hair, which made me frown since I knew that the inside joke was intended to make fun of me. I adamantly refused to comply, however he and his friends insisted, while making use of the limited time to pressure me into enacting the joke. Eventually, I did so and they burst into laughter. For a while, I mindlessly laughed along with them before snapping out of that illusion and scowling at my enemy before borrowing the pen, writing my name and giving it back to him.
