When others discuss the acne on your face, can you respond gracefully without embarrassment?

I will smile and stop this topic from going on. When I was in the sixth grade, I began to get pimples on my temples. I am a handsome guy, and I left a good impression on my classmates when I first entered junior high school. Later, acne eroded my face and neck, leaving a lot of acne marks, but most of my classmates didn't laugh at me. Only one punk in my class said to me at the flag-raising ceremony,' Shit! I tried to hit him, but I couldn't beat him, let alone put up with it at the flag-raising ceremony. It really hurts others' self-esteem to say that people are not short without hitting their faces.
