Gently, quietly, of course.
I used to work in a company with a mixed working layout. Open offices and sometimes a couple of closed rooms. After the elevator hall you had a door to get into the office. Our company occupied several floors in the building, so there were a lot of people coming in an out to go to other floors, to external appointments, etc.
This door at our office had a lot of traffic. Myself, I went often through that door. And yes, every time I went through I tried to catch, stop, or dam the slam of the door.
A friend of mine whose workplace used to be close to that door, told me that every morning she knew when I had arrived, because she could tell by the gentle sound of the closing door.
That is, in a way, Antonio's choice.
Rotterdam is the place, architecture is the work, sailing is the passion, Margreet is the love, and Gaizka is the pride and the connection to life
