Dear Professor,
My name is Yoewon (Aly) Yoon and I am a student in your Freshman Orientation class. I am aware that during club hours, our class will be taking a trip to the museum for an Enrichment Workshop. However, I will be unable to attend this workshop. Usually I have work during that time and was unable to take the day off. However, I am willing to go with another FRO class to their workshop or go on one by myself on whatever day you would like me to. I apologize for the inconvenience and hope that I can make the absence up. Thank You.
Sincerely,
Aly Yoon
