His behavior like a mad dog scared the people around him.

He checks the threads on Kenmo every day.

Category theory is a branch of mathematics that studies structures and their relationships.

When I saw his performance for the first time, I was moved by his talent.

He is opposed to an authoritarian government.

He is a famous licensed architect who has designed many wonderful buildings.

There is still an old ticket machine left at the station.

He started a new life as a former prosecutor.

He is the driving force behind this project.

My dog loves his new kennel.
