So, earlier this week, a cosplayer acquaintance of mine called me, and inquired about photography services for an event she was hosting. It was an honorary high school diploma ceremony for her boyfriend, who was unable to finish his diploma, due to a terminal illness. I spent some time talking with her, and followed up with a proposal. I gave her a 20% discount considering the situation, but her mother just called me this morning and said they won't be able to do it, because the event grew way larger than anticipated (50 people became 150), and they couldn't afford it, saying they were sure other photographers would be there. She did thank me for my time and said they were considering having a wedding and would love to keep me in mind for that. I was personally very honored to have been considered for this, and was looking forward to capturing this moment for her. If it wasn't 2 hours away, I would maybe have considered doing it even cheaper, or even pro bono, but in the end, she is only an acquaintance, and I do have to run a business. But... I feel bad. Should I? Is there something else I should do here?
