Traffic Jam

It was Tuesday evening and I left office bit early thinking I could go home early and relax with a cup of coffee and a Episode on Friends on TV3. And out of nowhere I found myself stuck in traffic. It was not a typical “rush hour” time of day and normally traffic does not get backed up like this. I figured there must be an accident or some type of serious incident up ahead just out of sight. I was all alone in my car slowly creeping my way forward, bumper to bumper, continually looking for the flashing lights of ambulances and police cars; the telltale signs of a roadway incident. Then, all of a sudden, traffic began to move normally again. There is no sign of an accident, incident, or any other cause of the slowdown in traffic. What happened? By now I was in this traffic for more that an hour and half, normally it takes only 35 to 40 minutes for me to come home... What must have happened??

Anyways, after 2 hrs and 30 minutes, I finally reached home and had nice cup of coffee with any FRIENDS. and still wondering what must have happened????
