Don't slide tackle from behind

A childhood memory that always comes to mine has to be when I got my first red card in soccer. My family was in Houston, Texas on vacation. We woke up at 5 am on a Saturday to fly back to Pennsylvania so we can make it to my game on time. We rushed through the airport got on a 4 hour flight to make it in time. We landed in Philadelphia at around 9 am and my game was at 10. The problem was the field was about an hour outside Philadelphia. My mom and dad went as fast as they could while I put my uniform and cleats on in the back. We got to the game and everyone took the field but it hadn't started yet. I ran right from the car to my position (center back) and started the game. 5 minutes go bye and a kid gets on a break away. I slide tackle him from behind. All I see is the referee show me a red card. My mom and dad were in disbelief. All the time we spent rushing for me to get thrown out of a game in the first five minutes. The funniest part about it is all they could do was laugh.
