Nikaido-san is my best friend.

There is a deep relationship between him and me.

He is in mourning for his father.

He injured his perineum in a bicycle accident.

I will attend the lecture tomorrow.

This year's year-end party was very fun.

I was chosen as a member of that committee.

Emiko is my best friend.

There is a farewell party for Mr. Tanaka tomorrow.

I am planning to go to a drinking party tonight.
