THIS IS ALL MY OPINION, feel free to argue or diagree, it helps build self esteme
It is exceptionally difficult not to feel aggresive or angry about something. I am a active participant in soccer and FIRST, both of which I have periods of anger towards something/one. The thing that seperates GP from flat out rudeness is how you control your anger. If I really need to, I will run it through my head a few times and then think out why that happened, or forget it all completly.
If you can keep a bright and welcoming attitude to a person who angers or annoys you, I feel that is defenitly the hight of GP.
I'm proud to say that I witnessed no unGP at Colorado, even the winners of the Finals actually came over to congradulate us when our robot hurdled for the first time in its final match of the day. I thought this was an amazing feat.
