One place I worked, till 1992 at least, had offices with doors for all the engineers. I loved it but, if I kept my door closed for too long, I often felt others thought I was hiding or goofing off.

If I kept my door open, I would still get distracted by people walking by. Even if they didn't say anything, they'd look in which would catch my eye.

Visiting my dad's work in the 1980's, what I distinctly remember is not only office doors, but that everyone had a busy light outside that they could toggle from a switch on their desk. Presumably so they could close the door but still let others know they were fine with interruptions. The lights probably did not ONLY exist for visiting kids to have something to play with.
