Interesting.....
I have had problems with altercations and raised voices. Up until recently I couldnt even watch 2 people argue in raised voices on a tv show. Seriously. It made my heart race and I became very anxious. I had to change the channel.
Loud voices are intimidating and frightening to a young child and sometimes I think the child in me is afraid of getting yelled at or getting hurt when a voice becomes loud in tone.
So for me, the loud angry voices trigger painful memories. As for the loud obnoxious people who arent angry just loud..it does it too sometimes. I used to snap some tart remark back, such as 'God could you be any louder?" NOw I just have to shut my eyes and walk away.
