Have you ever had to choose between your two best friends? That's what I had to do. Kate and Maria, my two best friends, were both
running for student council president. I tried to support both of them, but I could vote for only one person in the end. Both of them wanted my
help in persuading other students to vote for them. One day Kate cornered me and said, "Time to put your cards on the table. Are you voting
for me or Maria?
