My house is near the mountains.

He is playing soccer in a club team.

This morning, the train was delayed due to a personal injury accident.

He injured his leg in a traffic accident.

My teammate is very helpful.

We understand that teamplay is necessary for us to succeed.

He has expert knowledge.

He is studying computer science at a specialized school.

He is a specialist fool, with no interest in anything outside his field.

He couldn't say anything about issues outside of his field of expertise.
