Busy Status Bar

This reminds me of my first job in London looking after the network of a recruitment agency. The consultants got headsets for the first time and one got so annoyed about being interrupted when on a call - because you couldn't tell when people were wearing headsets the whole time - that she taped a big bit of card to the top of her headset saying "ON A CALL" that she could flip up and down depending on whether she was speaking to someone.

I had a coworker who felt free to interrupt me at any time. Even if I were frowning and leaning in to read some code word for word, he’d stop by to talk about nothing. I started wearing headphones when I was in concentration mode and that didn’t help. Then I wrote “DO NOT DISTURB” on a post-it note, stuck it to my headphones, and dug in for some thought-intensive hacking. He came to my desk, pulled the note off the headphones I wore, and tapped me on the shoulder, laughing. “Hah, look what someone taped to your head!”

We both learned something about the limits of my patience that day.
