I stress the common case for the same reason that when I construct sentences, I try to put the main point up front, and save the side comments for later. Example:
"I ran into Bob while walking to the store."
"While walking to the store, I ran into Bob."
The point I'm trying to get across, in this case, is that I ran into Bob. I try to do the same with code.
"I ran into Bob while walking to the store."
"While walking to the store, I ran into Bob."
