People are not always behind you because they are weak. Sometimes they just haven't learned how to put out as much as you do. And then if it is a rather nippy morning, they may be behind you simply because they are clearing their nostrils. Furthermore, the only point where I want to lead is as we cross the finish line. I'll be glad to let you cut a hole in the air for me to follow through right up to the end, but then the last quarter mile belongs to me.
