.... when you lost your headphones and you realize that the world is too noisy.

That's sucks

I could not work at my former office without headphones. My boss hated me wearing them, but loved any background noise no matter how distracting it was. I was glad he worked from home most days, but hated the days he was in the office (he sat in the cubical behind mine and would constantly talk softly to get my attention, not even loud enough to be heard over the background noise let alone when I have headphones on so I can concentrate on what I was working on).
