I'm made of ice and I glow?

I'm easily antagonized by things and when I get pissed off I become less rational and my language deteriorates in to even more foul language.

I take things at face value, if someone says they're due home at this time or will finish work at this time and I know how long it should take for them to get home, reach me whatever I expect them to be on-time. I also expect people to pay me back on time or to do what they said they would.

I come across as remarkably confident but secretly when I take severe knocks (such as missing out on a good job offer when I know I gave a good interview) I need lots of motivational help to get me to do so again.
