It’s not corporatizing, it’s simply respecting people’s time. Maybe I am just watching TV, but I’m doing that after a long day at work and don’t want an impromptu guest I need to entertain. Nor do I keep my house in a state to have company at the drop of a hat.
Drop ins were cool in college, but as an adult, it’s not so fun.
I have family with kids and their door is always open. They are very much adults with jobs, kids and other commitments.
