Generally, I am a very easygoing guy. The only thing that really pushes my buttons is prejudice and close-minded people, and even then, I know how to hold my temper. I try to be open and understanding of everything, and I try to help others understand when I see an opportunity to bridge a gap, but if the other people involved are being stubborn or vicious, I will either walk away or refer the issue to higher-ups as I feel necessary. I'm no kid, and I know when it's time to get an authority and when the best thing is to let something fizzle and die naturally. Don't feed the trolls, kiddies. Otherwise, it takes a LOT to really get under my skin. I have seen enough in my life that I am very hard to surprise or offend, and I like to help, which often gets me involved with amazing and horrible things going on in the lives of those around me, sometimes in equal measure.
So, tl;dr There isn't a lot that really annoys me, and generally, I try to view any such things as either lessons for me to grow or lessons I can help teach others (usually both, )
