PULK / PULL REVOLVING DOORS

There are barn doors

And there are revolving doors

 

Doors under rudders of big ships

And there are revolving doors

 

There are doors that open by themselves

There are sliding doors
And there are secret doors

 

There are doors that lock
And doors that dont

 

There are doors that let you in and out
But never open

 

But there are trapdoors

That you cant come back from
