I was surprised when I saw his dirty room.

I bought new at-home clothes.

The adult son who still lives at home is causing trouble for his parents.

This building is surrounded by firewalls.

I thought his plan was perfect, but in fact there were some flaws.

This retaining wall is designed to withstand earthquakes.

His favorite vase is placed in this niche.

The walls of this room are painted white.

The history of the Berlin Wall is very interesting.
