Could you tell me a time you felt angry?

Right, so I suppose to start with I want to say I am not a really angry person.  I think most people that know me wouldn't say I was an angry person and think I'm pretty chilled out. But, in saying that I think I do have a really bad temper, I think that's the ginger gene, which I definitely get from my dad I think. To pick a specific time I felt angry I find difficult.  As I have a long fuse my anger comes from more a build up of frustration, which leads to a big outburst lasting a few seconds.  An example of something which specifically makes me angry is if someone was to say anything negative against someone who I am very close with......I get very protective and often say things which are probably out of order. For instance, to members of my family who say things to my brother which will make me loose the rag. But, I can think of other times when I have been angry. When I have been annoyed at my girlfriend...oh god she is going to kill me for saying that.  However, I wouldn't say that's anger. I would say anger is when I get a proper surge of rage, with no off switch, until it's run its course but it always passes. I don't ever get physical, I have never been in a fight in my life and couldn't batter a fish. I do think I get a bit of red rage, calm down and then feel really shit because I hate losing my temper.
