When I first read this, I couldn't think of anyone specific, thus had one of those oh shit, maybe that's me then!? moments.
Then I remembered all those years ago working in northern call centres, where it seemed like anyone with half a brain could easily climb the promotion ladder, with those rewards seemingly nearly always going to the brashest, loudest and most vocal women.
These folks would then inflict their voluminous tones on us poor support staff, raising their voices further to ask us to fulfill whatever trivial task they were not allowed to do themselves - increasing the volume depending on their perceived urgency or importance of the issue at hand.
Occasionally I saw some sweet payback, ironically by staying silent save for stifling a giggle. We also had all the equipment the company didn't trust to be used on the operational floors, and got to see the same folks go from proudly colour printing some fancy new team tool, to their confusion when said paper was not laminated or returned after being fed into the big shredder!
As a youngster I certainly had the capacity to be louder than average, mainly because my mother had begun going deaf in one ear from as long as I can remember, then the other began to go next. Hence it was just automatic to talk loudly to avoid having to repeat yourself, but I also realised what I was doing.
Then after I leave home, my mother goes and gets one then another of what I can only describe as Frankenstein-esque implants, that aid hearing through bone conductivity I think.
Over the years the technology has improved, so bizarrely as she got older her hearing has got better - but unfortunately my childhood reflex still kicks in when talking to her, and the more important / less repetitive I want to be, the louder I instinctively speak, which is awkward when she physically winces from now painfully loud volumes!
