Someone else sent me this.

One day I hopped in a taxi and we took off for the airport. We were driving in the right lane when suddenly a black car jumped out of a parking space right in front of us. My taxi driver slammed on his breaks, skidded, and missed the other car by just inches!
The driver of the other car whipped his head around and started yelling at us. My taxi driver just smiled and waved at the guy. And I mean he was really friendly. So I asked, "Why did you just do that? This guy almost ruined your car and sent us to the hospital!" This is when my taxi driver taught me what I now call, "The Law of the Garbage Truck." He explained that many people are like garbage trucks. They run around full of garbage, full of frustration, full of anger, and full of disappointment. As their garbage piles up, they need a place to dump it and sometimes they'll dump it on you.
Just shake it off. Be glad YOU'RE not that other guy.
