The key note speaker at Falls Church High School’s graduation on June 1 said that there are four or five days in every person’s life that he or she will never forget. Friday’s ceremonies, held at George Mason University, may very well count among them, as the star-struck high school graduates in attendance last Friday listened to the address given by actor Ben Affleck. For graduate Joe Kindregan, the student responsible for Affleck’s attendance, there is no debate.
