I work part time at a bar on the weekends, and I get a ton of drunk idiots on a regular basis. This last Thursday, two girls rolled in together around 1 a.m. One girl had a surgical mask on her face and the other girl was smiling. Thinking they were drunk and being silly, I asked the girl with the mask if she was sick. She replied and said, "You don't wanna know." Jokingly, purely jokingly, I said, "Ha, is it SARS?" All of a sudden her friend starts yelling at me, telling me she has cancer and needs to wear the mask so she doesn't get sick since her immune system is so weakened by the chemotherapy.
I looked at her in shock and profusely apologized. She wouldn't drop it and said, "If you don't believe me I'm losing my hair," while pulling off her hat to expose her balding head. I felt like such a jerk. I apologized over and over but I still feel guilty. Can I be forgiven?
