I have no choice

Yesterday, I went to the post office in the morning.

Then, I had a lunch with my mother.

We bought lunch boxes and ate at my office.

A client came to bring documents in the afternoon,

A student came to take lesson in the evening.

Today, I have to go to Iida because of Shiho-shoshi association's job.

Under this social situation, I don't want to go.

But, it's association's job, so I have no choice...
