My Room on a Street (verse 4)

I hear the water running inside a sewer drain(19)
I hear a classroom full of teenagers cheering
From the 4th story of a building(20)
Techno fills the air as we pass the cellphone store(21)
We get to the station
In front they sell flowers and play pop music(22)
There are footsteps and look held beeps and short clicks of tickets moving through machines(23)
We pass through
And on to the hum of an escalator(24)
