There are always a bunch of different kinds of people you find in your group of friends; there's the carefree friend, the studious friend, the stoner friend and then there's the person who gets all worked up, all the time because they just can't keep their temper in check. However, they're also bound to be some of your closest friends thanks to their big hearts and their honesty, so it always balances things out. If you've noticed these symptoms, you're probably friends with an angry young man/woman.

1. You maintain a completely neutral stance on most social issues when you're around them because you know they'll bite your head off if things get heated.

2. If you happen to be sitting next to them at a traffic jam, you're guaranteed to hear the most creative curses in your life, which is always useful!
