It is important for each person to fulfill their role.

I went to see a movie by myself.

Watching a movie alone is enjoyable.

This is the most beautiful flower.

That person is my friend.

He is a person who never forgets to respect others.

I deeply respect him.

He and his brother look so alike, they seem like the very same person.

I go jogging every day.

He solved the problem solely by himself.
