You really are an idiot.

On April Fools' Day, I surprised my friend with a joke.

He is a 'word processor idiot', his handwritten characters are terribly hard to read.

You really are a stupid man, aren't you?

My personal thought is that everyone should be treated equally.

He values his private life.

He holds a personal grudge against me.

Using the private railway makes commuting very convenient.

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

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