I believe everything happens for a reason. Everything you do affects how you do things in the future as well as what maybe other people do. So next time you cut someone off while driving, yell at some random person in public, or say something offensive to a friend or someone you care about, think about their perspective and how they would feel. You never know who you might actually be talking to or helping if you be the bigger person. You would be surprised how often the past can come and haunt you, whether you realize it at the time or not.
