Rescheduling Interview?

My ED Duke alumni interview is in 2 days and I just found out that my monthly meeting for my internship is at the exact same time and date. While I technically can miss the meeting, I would rather not. Is it inappropriate to reschedule, or does it reflect poorly on myself? The interviewer did offer two dates, Wednesday and Thursday, and I let him decide. To reschedule, or not to reschedule, that is the question! I am agonizing over this decision, and I welcome any input!!!

It’s perfectly fine to reschedule. Just explain your situation and all will be well.
