Peter explained, “We started seeing each other less and less. The friendship was just over.”

Sometimes friendships break   (4)   suddenly from a disagreement or move to another place.

Alice said, “The end of our friendship was a gradual thing. I moved from one side of the city to another. From then on we   (5)   made a phone call. We met less and less. At last our friendship ended.”

Jack said, “When I moved to Seattle after college, our friendship died.  (6)  of us were always busy with new jobs, so we didn’t keep   (7)   touch with each other. Our friendship was so dead that I didn’t call him even if I went home.”

Yet the biggest problem to a friendship is change. Lillian Rubin in her book Just Friends says,“ Generally it’s true that friends will accept each other if they both remain what they were when they met. However, if they change in   (8)  directions, the friendship most probably will be lost.”
