| One day I hopped in a taxi and we 1 for the airport. We were driving in the right lane when 2 a black car drove out of a parking space right in front of us. My taxi driver slammed on his brakes, skidded, and 3 the other car by 4 inches! The driver of the other car whipped his head around and started yelling at us. My taxi driver just smiled and 5 at the guy. And I mean,he was really 6 . So I asked, "Why did you just do that? This guy almost 7 your car and sent us to the 8 !" This is when my taxi driver taught me 9 I now call, "The Law of the Garbage Truck." He 10 that many people are like garbage 11 . They run around full of garbage, full of frustration, full of anger, and full of 12 . As their garbage piles 13 , they need a place to 14 it and sometimes they'll dump it on you. Don't take it personally. Just smile, wave, wish them well, and move on. Don't take their garbage and 15 it to other people at work, at home, or on the streets. The bottom line is that 16 people do not let garbage trucks take over their day. Life's 17 short to wake up in the morning with 18 . So....Love the people who treat you right. 19 for the ones who don't. Life is ten percent what you make it and ninety percent 20 you take it! | |||
