I knew a guy in high school with this condition. I felt bad for him, because he had cysts all over his face, and his classmates were ruthless with their teasing. His cheeks appeared absolutely yellow, and kids thought he might be contagious.
He could not get a date for the prom because he was viewed as hideous, and even the girls who liked his personality were put off by the social stigma. I didn't care about that, so I asked him to the prom myself.
People stared at us in disbelief when we showed up together. They could not believe he had gotten a date, and they could not believe that I agreed to go with him.
We blocked them out and had a great time. We became close friends, and since people saw that I did not catch his condition by associating with him, they were a little less reluctant to approach him.
