#2 is probably the one that stands out the most to me:
I think this is very important, at least I know it's very important to me. I can deal with disagreements till the cows come home and I'm fine with people expressing their hurt and anger by talking about it, or even pouting if talking isn't possible. However, as soon as someone yells at me I get really angry and hurt and pretty much shut down. It also feels like a major violation of trust to me.
I suppose a lot of it is personal expression style. When I'm angry, beyond the point of being able to continue talking about it rationally, I become really icy and sarcastic. I can in turn deal with that from other people (not that it's a good thing at all; it certainly isn't). I don't do the yelling thing and when other people do it freaks me out big time and my respect and trust for that person suffers a major blow.
