My Room on a Street (verse 3)

I tap aluminum pipes that run a long a building(13)
and a pole carrying an irrelevant road sign(14)
I brush a black car parking gate(15)
On my left a construction site(16)
A man talks inside his dust mask
I can hear the drilling of drills
And the banging of hammers on steel
I knock on wood(17)
I step on a loose cinder block hiding a storm drain(18)
