My grandfather used to till his privately-owned rice field.

My personal thought is that everyone should be treated equally.

He values his private life.

He was born as an illegitimate child and experienced many difficulties.

He holds a personal grudge against me.

Using the private railway makes commuting very convenient.

He is majoring in psychology.

Gaku is my best friend.

He understands the importance of learning.

He has a deep interest in archaeology.
