I am spending the happiest days of all.

The room rent is too high, so I'm looking for a new apartment.

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.

My room is on the second floor.

He is good at playing the chromatic scale on the piano.

This staircase is very beautiful.

My apartment is a five-story building.

I needed to calculate the factorial of 5 for a math problem.
