It was regrettable

Yesterday morning, I applied for the registration of real estate and then went to the Legal Affairs Bureau.

In the afternoon, I organized some documents at my office.

Last night, I was planning to hold a Korean seminar at our café; however, it was canceled due to the low number of attendees, which was very regrettable.

This morning, I plan to take out the trash and then do the laundry.

In the afternoon and evening, two elementary school students will come to take English lessons, and an adult will come to take a Korean lesson in the evening.
