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.

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

He holds a personal grudge against me.

Using the private railway makes commuting very convenient.

He likes to take a walk in the park at dusk.

He is a perfectionist, so he is very strict about his work.

He played a perfect fifth scale on the piano.

I'm sorry, but I don't speak Japanese.
