Brain Surgery<br>A few years ago, my wife left town for a few days. While she was gone, I started having terrible headaches. I decided to wait it out until she returned to town. Immediately after she returned, we ended up going to the hospital. I had brain surgery and ended up being glad that I waited for her.
If his wife didn't come he wouldn't have gone to the hospital.
