One drive that changed our lives

It was 5th of March. Our results were out, my friends cleared their exams. I got an improvement exam in mathematics. Actually I flunked in mathematics to be precise. It was okay, many other students flunked too! Anyhow, I was upset and so my lovely friends gave me a company to home and tried cheering me up. Sweet.
We ordered some burgers from the McDonald's. Just when we were waiting for the food and cracking jokes (my mood was better then) the doorbell rang. It was my brother's best friend. I consider him my brother too ! My girlfriends and they convinced me to go for a drive with them. I did. :) ..
He wasn't driving fast, he was flying slow. Just when .. BOOM !!
