Catch me if you can!

Ok, so I was on my run this evening and I noticed this guy about half a block behind me as I rounded the corner onto the next street. He was a typical zoobie and obviously was trying to catch up with me because I could hear his breathing and footsteps getting louder. I came to an intersection and could have made it...but decided to wait the light out and let him catch up to me...I like having a little competition ;) When the light changed, I took off as usual and could hear him keeping up with me. I got to the next light about 4 minutes later and turned to see where he was...but he was no where to be seen.
