Imagine all twelve standing in a line. The first person in line walks down and shakes everyone's hand, that's 11 handshakes, and then steps aside. The next person does the same but only shakes 10 hands because they have already shaken the hand of the first person. This continues until the second to last person in line shakes the hand of the last person in line.
