No, it definitely doesn't equal grumpy.
I really need my quiet time.
The best way I can explain the way noise comes across to me is that there is no such thing as background noise. All noises are foreground.
And I also work in an open plan office, with about 40 people. So many conversations, so much computer-related noise, and phones, and equipment buzzing, and...
Fortunately I'm in a corner. However much noise there is, I can bear it better if it's only coming from one direction. But it's still not easy, and I get home and just need silence!
But it doesn't mean I'm grumpy!
I hope you start feeling better soon, Tipp. And that the acupuncture helps.
